Description of the Invention: [Technical Field of the Invention] The present invention relates to an antenna device. [Prior Art] Patent Document 1 discloses a zero sequence converter. The zero sequence converter is provided with a magnetic chip, a secondary winding wound around the magnetic chip, and an end joint terminal for winding the end of the secondary winding. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2000-348957 (Summary of the Invention, Patent Application, No. 0025, etc.) [Explanation] The problem to be solved by the invention is as described in Patent Document 1, and is wound around a magnetic chip or the like. The end of the winding is wound around a bundle terminal called an end joint terminal or the like. Thereby, the winding can be electrically connected to other electronic devices. However, when the winding end wound around the magnetic chip or the like is wound around the bundle terminal and connected, the part of the winding is formed to protrude outward from the flange portion of the magnetic chip or the like, for example. A case where a so-called "airline wiring portion" (flying-lead "flying line portion" is formed. Then, if the aerial wiring portion is formed, for example, in an antenna device or the like for a keyless entry system of a vehicle, the possibility of occurrence of wire breakage in the air wiring portion and its surroundings becomes high. Due to vibration or heat applied to the antenna device, the empty t-wiring portion of the winding and its surrounding portion are likely to repeatedly collide with the edge of the flange portion, or the winding is easily broken. 1344659 ... In the antenna device of the prior art, for example, a portion of the winding that is highly dangerous in the air is folded as a twisted wire structure to improve the strength. Or, a drilling agent is applied to a portion of the winding which is a dangerous portion of the air wiring portion. (Processing agent, however, in order to form a twisted wire structure after winding the lane, it is necessary to add a complicated structure for forming the strand. In addition, in order to apply an adhesive (treatment agent), it is necessary to add a process for performing the coating and drying and solidification. When these countermeasures are applied to each antenna device, the antenna device is used. The manufacturing cost is increased as compared with the manufacturing cost of a general coil component. The inventors of the present application conducted the following research based on the problem of such an antenna device. Thus, the present application was completed. The tenth diagram is an explanatory view of the type of the winding method in the antenna device of the prior art. The winding members of the four antenna devices of the tenth (A) to (D) are provided with a cylindrical shape. The reel portion 41 and the pair of flange portions 42 disposed at both ends in the axial direction of the reel portion 41. The pair of bundle terminals 43 are disposed in a disc-shaped flange portion 42 in a posture parallel to each other*. In the tenth diagram (A), the pair of bundle terminals 43 are disposed on the same side of the flange portion 42 when the flange portion 42 is appropriately divided into two portions. Usually, for example, two points As shown by the scribe line, the pair of bundle terminals 43 are disposed at a position of an angle of 90 degrees or less with respect to the reel portion 41. The winding 44 is first wound around the bundle terminal 43 on the upper side of the upper left side in the drawing while applying tension. Then, it is wound on the reel portion 41 in the counterclockwise direction, and finally wound on the end terminal 43 on the upper right side. In the case of the tenth diagram (A), the bundle terminal is wound on the start side 1344659. a portion between the portion on the 43 and the portion wound on the reel portion 41, the portion of the winding 44 (hereinafter referred to as opening) The lead-out portion 45) of the start-side winding 44 does not become an aerial wiring portion that protrudes outward from the flange portion 42. The portion wound around the reel portion 41 and the portion wound on the end portion of the bundle terminal 43 are The portion of the winding 44 (hereinafter referred to as the lead portion 46 of the end side winding 44) does not become an air wiring portion that protrudes outward from the flange portion 42. In the tenth diagram (B), Similarly to the tenth diagram (A), the bundle terminal 43 is disposed on the same side of the flange portion 42. The winding 44 is first wound around the beam terminal 43 on the upper side of the upper left side while applying tension, and then It is wound in the clockwise direction on the reel portion 41, and finally wound on the end terminal 43 on the upper right side. In the case of the tenth diagram (B), the lead-out portion 45 of the start side winding 44 is rolled up. When the diameter of the shaft portion 41 is increased, the root portion of the protruding portion of the reel portion 41 with respect to the start side bundle terminal 43 becomes the air wiring portion when it is on the upper side in the drawing. The lead-out portion 46 of the end side winding 44 becomes an air wiring portion in most cases. In the tenth diagram (C), the pair of bundle terminals 43 are disposed on the opposite sides (opposite sides) of the flange portion 42. Specifically, the pair of bundle terminals 43 are disposed on the flange portion 42 at positions on the opposite side of the intermediate space from the reel portion 41. The winding wire 44 is first wound around the beam terminal 43 on the start side of the upper left side while applying tension, and then wound on the reel portion 41 in the counterclockwise direction and finally wound around the end terminal 43 on the lower right side. In the case of the tenth figure, the lead-out portion 45 of the start side winding 44 does not become an air distribution portion. The lead-out portion 46 of the end side winding 44 is, in most cases, an empty wiring portion. The pair of bundle terminals 43 are the same as the tenth figure (c), and the opposite side (opposite side). The winding 44 is wound on the reel portion 41 in the two-direction direction on the bundle terminal 43 on the start side of the upper left on the upper side of the applied tension ==, and finally wound on the terminal 43 of the end 44 on the lower right side. In the case of the tenth diagram (D), the diameter of the bow-out portion 45' of the start side winding becomes larger at the diameter of the reel portion 41 so that the reel portion 41

:對於開始側束端子43的突出部分的根部在圖中處於上側 時’成為空中配線部。結束側繞線44的引出部位46不會 成為空中配線部。When the root portion of the protruding portion of the starting side bundle terminal 43 is on the upper side in the drawing, it becomes an air wiring portion. The lead-out portion 46 of the end side winding 44 does not become an air wiring portion.

如該第十圓（Α)〜（D)的四個例子所示，現有技術下的天 線裝置的繞線44上，有可能會形成從凸緣部42向外側突 出的空中配線部。特別是，如第十圖（c)及（D)所示那樣，在 一對束端子43配設於凸緣部42的相反側上的情況下，即 使向捲轴部41的捲繞方向為順時針方向或逆時針方向也 會在繞線44上形成空中配線部。相對於此，在一對束端子 43配設於凸緣部42的同一側上、且採用第十圖（A)的捲繞 方向的情況下，不會形成空中配線部。但是，在第十圖（B) 的情況下形成空中配線部。另外，在第十圖（A)、（B)的情況 下，為了防止空中配線部的產生必須以第十圖（A)的方向捲 繞繞線44 ’因此天線裝置的製造工序上會產生制約。如果 要不使空中配線部形成的話，則繞線44的捲繞方向或&數 被限定。這樣在現有技術下的天線裝置中，在一對束端子 43配設於凸緣部42的相反側的情況下，與一對束端子43As shown in the four examples of the tenth circle (Α) to (D), in the winding 44 of the antenna device of the prior art, an air wiring portion protruding outward from the flange portion 42 may be formed. In particular, as shown in FIGS. 10(c) and (D), when the pair of bundle terminals 43 are disposed on the opposite side of the flange portion 42, the winding direction of the reel portion 41 is The air wiring portion is also formed on the winding 44 in the clockwise direction or the counterclockwise direction. On the other hand, when the pair of bundle terminals 43 are disposed on the same side of the flange portion 42, and the winding direction of the tenth diagram (A) is employed, the air wiring portion is not formed. However, in the case of the tenth diagram (B), the air wiring section is formed. Further, in the case of the tenth drawings (A) and (B), in order to prevent the occurrence of the air wiring portion, it is necessary to wind the winding 44' in the direction of the tenth diagram (A), so that the manufacturing process of the antenna device is restricted. . If the aerial wiring portion is not to be formed, the winding direction or the number of the windings 44 is limited. Thus, in the antenna device of the prior art, in the case where the pair of bundle terminals 43 are disposed on the opposite side of the flange portion 42, the pair of bundle terminals 43
