(b) in addition, compared in the magnetic field that the line length other ring-shaped conductors longer than path ring-shaped conductor 31 generate,
The magnetic field that the line length path ring-shaped conductor 31 shorter than other ring-shaped conductors generates is small.Therefore, with this configuration, the shape in magnetic field
At few the case where obstruction by the eddy current generated in metallic object 2.Therefore, as the decline of the inductance caused by of metallic object 2
It is few, furthermore it is possible to realize inductor electric bridge with low-loss tape winding 3 and have the electronics of the inductor electric bridge
Equipment 301.
(c) in addition, in the present embodiment, because insulating substrate 10 is thermoplastic resin, such as (2) institute in Fig. 4
Show, matchingly easily capable of carrying out plastic processing to shape with installation condition (bumps etc. of installation destination), (bending adds
Work).
(d) in the present embodiment, comprising being respectively formed at the path ring-shaped conductor 31 of multiple substrate layers 12,13 and big
Diameter ring-shaped conductor 32 and constitute tape winding 3.With this configuration, can insulating substrate 10 formed have given winding number with
And the tape winding of inductance.
(e) in the present embodiment, the different multiple ring-shaped conductors of internal-and external diameter (path ring-shaped conductor 31 and major diameter ring
Shape conductor 32) it is configured along Z-direction.In addition, from Z-direction, multiple ring-shaped conductors (path ring-shaped conductor 31 and big
Diameter ring-shaped conductor 32) it does not overlap each other.With this configuration, ring-shaped conductor (path ring-shaped conductor 31 and major diameter ring-shaped conductor 32)
Face it is not opposed each other, therefore the layer capacitance between multiple ring-shaped conductors is small.
Then, illustrate to be applied with inductor electric bridge 101 electricity in the case where being allowed to generate curved external force referring to figure
The relationship of sensor electric bridge 101 and metallic object 2.Fig. 5 (A) is inductor electric bridge 101 and the metallic object 2 shown before being allowed to bending
The partial sectional view of relationship, Fig. 5 (B) are the portions for showing the relationship of the inductor electric bridge 101 and metallic object 2 that are allowed to curved state
Divide cross-sectional view.
As shown in Fig. 5 (B), inductor electric bridge 101 is bent into L-shaped (by first along the longitudinal direction of insulating substrate 10
The side interarea VS1 is used as inside).At this point, second side interarea VS2, which is deformed into, to be stretched due to the bending displacement of insulating substrate 10, the
One side interarea VS1 is deformed into compression.Along with the stretcher strain of the side the second interarea VS2, it is located in the Z-axis direction main by second
The major diameter ring-shaped conductor 32 of the position of face VS2 generates displacement, so that expanding towards the both ends in the longitudinal direction of insulating substrate 10
(referring to the hollow arrow DF2 of Fig. 5 (B)).In addition, being located in the Z-axis direction along with the compressive deformation of the first side interarea VS1
Path ring-shaped conductor 31 by the position of the first interarea VS1 generates displacement, so that shrinking (referring to the hollow arrow of Fig. 5 (B)
DF1)。
Therefore, even if in the curved situation as Fig. 5 (B) of insulating substrate 10, from Z-direction, path is cyclic annular
Conductor 31 and major diameter ring-shaped conductor 32 will not be overlapped (face does not overlap each other), therefore path ring-shaped conductor 31 is led with major diameter ring-type
The variable quantity of layer capacitance between body 32 is small.
In addition, in the present invention, as shown in Fig. 5 (B), the relatively large other ring-shaped conductor (major diameters of conductor area
Ring-shaped conductor 32) configuration than path ring-shaped conductor 31 further from the position of metallic object 2.Therefore, even if in inductor electric bridge
In the case that 101 are bent and make other ring-shaped conductors (the major diameter ring-shaped conductor 32) deformation of conductor area greatly, tape winding 3 and gold
The variable quantity for belonging to the parasitic capacitance between body 2 is also small.
In turn, by the curved situation of inductor electric bridge 101, path ring-shaped conductor 31 is also deformed, and conductor area can become
Change.But with this configuration, with by the relatively large other ring-shaped conductors (major diameter ring-shaped conductor 32) of conductor area close to metal
The case where body 2 configures is compared, small with the variable quantity of the associated parasitic capacitance between metallic object 2 of variation of conductor area.
Inductor electric bridge in the utility model is also possible to following structure.Fig. 6 (A) is that first embodiment is related to
The partial sectional view of another inductor electric bridge 101A, Fig. 6 (B) are the partial sectional views of the inductor electric bridge 101B of comparative example.
In Fig. 6 (A) and Fig. 6 (B), path ring-shaped conductor 31A, 31B and major diameter ring-shaped conductor 32A, 32B are large shown
Thickness.
As shown in Fig. 6 (A) and (B), path ring-shaped conductor 31A, 31B that inductor electric bridge 101A, 101B are related to and
The path that inductor electric bridge 101 shown in thickness ratio Fig. 2 (B) in the Z-direction of major diameter ring-shaped conductor 32A, 32B is related to is cyclic annular
Conductor 31 and major diameter ring-shaped conductor 32 are thick.Specifically, path ring-shaped conductor 31A, 31B and major diameter ring-shaped conductor 32A, 32B
Z-direction on thickness than stacking before each substrate layer Z-direction on thickness it is thick.In addition, inductor electric bridge 101A,
The insulating substrate 10 of inductor electric bridge 101 shown in thickness H1 and Fig. 2 (B) in the Z-direction of the insulating substrate 10A of 101B
Z-direction on thickness it is equal.
As shown in Fig. 6 (B), in the case where the face of path ring-shaped conductor 31B and major diameter ring-shaped conductor 32B is opposite each other,
The distance between path ring-shaped conductor 31B and major diameter ring-shaped conductor 32B L2 are than path ring-shaped conductor 31A and major diameter ring-shaped conductor
The distance between 32A L1 short (L1 > L2).Therefore, the inductor electric bridge 101B to comparative example be applied be allowed to generate it is curved
In the case where external force, the variable quantity of the layer capacitance of associated tape winding 3B is big with the deformation of inductor electric bridge 101B.In turn,
According to the present embodiment, from Z-direction, path ring-shaped conductor 31A and major diameter ring-shaped conductor 32A be not be overlapped, thus with electricity
The variable quantity of the layer capacitance of the associated tape winding 3A of the deformation of sensor electric bridge 101A is small.
In addition, by thickening the thickness in the Z-direction of path ring-shaped conductor 31A and major diameter ring-shaped conductor 32A, from
And the formation part of tape winding 3A becomes not flexible, improves to the mechanical strength of external force.In turn, by leading path ring-type
Thickness in the Z-direction of body 31A and major diameter ring-shaped conductor 32A thickens, so as to reduce the DCR of tape winding 3A (directly
Leakage resistance).
