New description: [New technical field] This creation is about a loop antenna, especially a coiled loop antenna for transmitting and receiving radio frequency identification (RFID). [Prior Art] A loop antenna is used for a device (e.g., a wireless tag) that wirelessly associates signals with an RFID or the like. The loop antenna is roughly classified into a flat type and a coil type using an FPC or the like depending on its configuration. A typical example of a planar loop antenna is a 1C card used as a ticket for a transportation agency. On the other hand, a typical example of a reel type loop antenna is used for an electronic device such as a mobile phone having an RFID function for reasons such as low cost. The coiled-type loop antenna has been conventionally known as, for example, the seventh figure (see Patent Document 1). The loop antenna 1〇1 shown in FIG. 7 has three wires I10 (11〇a, ii〇b, 110c) constituting each ring element of the triple loop antenna; β and an insulating casing 120 are mounted on The inside of the casing (not shown) of an electronic device such as a mobile phone of an RFID function. Further, the loop antenna 101 is provided with two first crimp terminals 130 which respectively connect the two electric wires 1〇 in series, and a pair of second crimp terminals 140' which terminate one end of the electric wire 10. Here, each of the first crimping terminals 130 is provided with a first crimping portion 131 ′ pressed into a first guiding groove provided in the outer casing 120 (not shown); and a second crimping portion 132 of the M429186 is pressed into the first crimping portion 131 ′ The outer casing 120 is provided with a second guiding groove (not shown); and a bridging portion 133 is associated with the first crimping portion 131 and the second crimping portion 132. The first crimping portion 131 includes a bottom plate (not shown), a bottom surface of the first guide groove, and two pairs of pressing blades 134 rising from the bottom plate. Further, the second crimping portion 132 includes a bottom plate (not shown), a bottom surface of the second guide groove, and two pairs of pressing edges 135 rising from the bottom plate. Further, at the first crimping portion 131 of one of the first crimping terminals 130 (the first crimping terminal on the upper side of the seventh drawing), the other end portion of the electric wire 110c is crimped and connected, and further, at the second pressing The connecting portion 132, the end portion of the electric wire 110a is crimped and connected. Further, at the first crimping portion 131 of the other first crimping terminal 130 (the first crimping terminal on the lower side of the seventh drawing), the other end portion of the electric wire 110a is crimped and connected, and, in the second In the crimping portion 132, one end portion of the electric wire 110b is crimped and connected. Further, the second crimp terminal 140 of one of the pair of second crimp terminals 14Q includes a crimping portion 141 and an external terminal portion 143 which are pressed into the first guide groove. Further, the other second crimping terminal 14 is provided with a crimping portion and an outer end portion 143 which are pressed into the second guiding groove. Further, each of the crimping portions 141 includes a bottom plate (not shown) and two pairs of crimping blades 142 rising from the bottom plate. At the crimping portion 141 of one of the second crimp terminals 140, the other end portion of the electric wire 11b is crimped and connected, and at the crimping portion 141 of the other second crimping terminal, one end portion of the electric wire 11〇c is Crimp connection. According to the loop antenna 1〇1 shown in the seventh figure, since the front ends of the electric wires 110 (110a, 110b, 110C) abut against the wall surface of the 4 M429186 of each guide groove, the crimping is continued to each crimping. Therefore, the degree of the ring length of each of the wires 110 can be made small. Further, as another prior example of the wound-type loop antenna, it is known as shown in Fig. 8 (refer to Fig. 8). The loop antenna 201 shown in the eighth diagram, as shown in the eighth (A) diagram, is provided with three electric wires 210 constituting each of the ring elements of the triple loop antenna. Each of the electric wires 210 is formed by coating the resin 212 on the conductor 211 as shown in the eighth (B) diagram. The three electric wires 210 are covered by the outer cover 213 to constitute a collecting electric wire 214. Further, the loop antenna 201 has a substrate 220 at both ends of the collective electric wire 214, and terminal portions 221 are provided at both ends of the loop antenna 201, and the terminal portions 221 are electrically connected to the ends of the electric wires 210. On the other side of the substrate 220, a wiring pattern (not shown) is formed, and the wiring pattern is electrically connected to one end of the electric wire 210 connected to the terminal portion 221 at one end and the other end of the electric wire 210 connected to the terminal portion 221 at the other end. The connection continues, and the connected wire 210 becomes a continuous and becomes a loop coil. Further, the terminal portion 221 and the conductor 211 of each of the electric wires 210 are preferably connected by soft solder.

In the electronic equipment using a reel type loop antenna and a mobile phone having an RFID function, the loop antenna is required to be thinned in recent years. Further, in the case of the loop antenna 201 shown in FIG. 8 , when the conductor 211 of each electric wire 210 is connected to the terminal portion 221, it is not easy to arrange the conductors 211 in the terminal portion 221 in a neat manner, and the alignment of the conductors 211 may be performed. problem.
