Most preferably at 45 ° relative to the long side direction of piezoelectricity film 403 and short side direction to 500, but as long as at the model of 45 ± 10 °
Enclose, just can use without any problems in practical.
Here, the characteristic of the PLLA forming piezoelectricity film 403 is illustrated.
PLLA is made up of chiral polymer.The main chain of PLLA has spiral structure.The molecularly oriented of PLLA is in uniaxial tension
Direction, because of the orientation of this molecule, there is piezoelectricity.And, the PLA of uniaxial tension should by producing at piezoelectricity film 403
Become and produce electric charge.Here, the strain producing at piezoelectricity film 403 refers to that piezoelectricity film 403 extends in the prescribed direction.
Now, the produced quantity of electric charge is determined by the dependent variable of piezoelectricity film 403.The piezoelectric constant of the PLLA of uniaxial tension is at high score
Very high species is belonged in Zi.For example, piezoelectric strain constant d of PLLA14By adjusting stretching condition, heat treatment condition, adding
The conditions such as the mediation adding thing, are obtained in that the such high level of 10～20pC/N.
Furthermore it is preferred that the stretching ratio of piezoelectricity film 403 is about 3～8 times.Implement heat treatment after the stretch, thus
Promoting the crystallization of the extended chain crystal of PLA, piezoelectric constant improves.Additionally, in the case of having carried out biaxial stretch-formed, logical
Cross the stretching ratio difference making each axle, be obtained in that the effect identical with uniaxial tension.For example, using certain direction as X-axis simultaneously
Implement the stretching of 8 times in the direction, and in the case of implementing the stretching of 2 times in the Y-axis orthogonal with this axle, for
It for piezoelectric constant, is obtained in that the effect roughly the same with the situation of the uniaxial tension implementing 4 times in the X-axis.Merely
The film that ground carries out uniaxial tension axially ruptures readily along stretching, therefore, it is possible to above-mentioned such biaxial stretch-formed next by carrying out
Somewhat increase intensity.
In addition, PLLA produces piezoelectricity by the orientation process of the molecule based on stretching etc., therefore do not need as PVDF etc.
Other polymer, piezoelectric ceramics carry out (Poling) process that polarizes like that.That is, the piezoelectricity being not belonging to ferroelectric PLLA is not
Generated electricity by the polarization of ion as the ferroelectrics such as PVDF, PZT, but origin is in the latent structure of molecule that is spiral structure
Make.Therefore, PLLA will not produce the pyroelectricity producing at other ferroelectric piezoelectrics.Further, PVDF etc. can become over time
Changing and the variation of piezoelectric constant occur, in the case of having, piezoelectric constant can significantly reduce, but the piezoelectric constant of PLLA becomes in time
Change extremely stable.Therefore, output charge amount does not interferes with surrounding environment.

In the case of like this compression sensor 41P～44P being set to the size less than operation screen 49, such as Fig. 8 (A)
Shown in, from the line of the end linking the respective long side direction of compression sensor 41P～44P in adjacent compression sensor to each other
Even if the region that section is in the outer part easily becomes the pressing non-detection region 93 that pressing also cannot normally detect.Specifically, if pressing
Press non-detection region 93 to be pressed, then several in compression sensor 41P～44P can produce the electricity with usual opposite polarity
Lotus, and export reversion.Therefore, in the case of being pressed in the non-detection region 93 of pressing, correct pressing detection becomes difficulty.
Therefore, in this touch panel 40P, by adjust the long side direction of each compression sensor 41P～44P size,
Configuration, being adjusted to the size in the non-detection region 93 of pressing, configuration affects few size in the operation of operation screen 49, joins
Put.
Specifically, as shown in Fig. 8 (B), the operation screen 49 of standard comprises to show becomes touch operation, pressing operation
The icon of object, the first image-region 91 of the symbol such as widget (Widget) and show and do not become touch operation, pressing behaviour
The status bars of the object made etc. represent the second image-region 92 of the symbol of status information.Thus, it is supposed that the non-inspection of aforesaid pressing
Survey region 93 overlapping with the first image-region 91 showing icon, widget etc., then become cannot be by for icon, a part for widget
The state of press operation, the operability for operator reduces and becomes problem.Therefore, in this touch panel 40P, pass through
Adjust size, the configuration of the long side direction of each compression sensor 41P～44P so that press non-detection region 93 not with the first figure
As region 91 is overlapping, and only overlapping with the second image-region 92.Thus, even if pressing non-detection region 93 and showing status bar
Deng the second image-region 92 overlapping, they are not the object of pressing operation, and therefore operator does not feels as operability fall
Low, the increase etc. of unreliability, can implement pressing operation to touch panel 40P.
So, in the touch panel of the present invention, size, the configuration of the long side direction of preferably each compression sensor are adjusted to
The position, the size that make pressing non-detection region are suitable.But, here, as operation screen (user interface), exemplified with only aobvious
One side side of the first image-region 91 being shown with icon etc. arranges the situation of the second image-region 92 showing status bar etc., also
Can use and the second such operation screen of image-region 92 etc. is set in the both sides of the first image-region 91, be operated by adjusting
Picture side makes the second picture area detection region non-with pressing being not provided with the object of pressing operation overlapping.
Additionally, carry on the small-sized equipment of the comparison that picture dimension as smart mobile phone is 4～7 inch
In the case of touch panel, as long as the size of the long side direction of compression sensor is operation screen about about 85%, press non-
The size in detection region and configuration are confined near the corner of operation screen being less than the region of the size of finger.Therefore, exist
Under such circumstances, even if there being the non-detection region of pressing also no problem on operation screen.
