- the other end of the first terminal 6 is disposed so as to overlap the other end of the second terminal 7 in plan view.
- the difference between one end of the first terminal 6 and one end of the second terminal 7 is set to, for example, 1 mm or more and 5 mm or less.
- one end of the first terminal 6 extends toward the outside of the frame body 3 from one end of the second terminal 7, so that an external member is directed from the upper side of the first terminal 6 toward the first terminal 6. Even if the contact is close and the force is applied in the direction from the first terminal 6 to the second terminal 7, the possibility that the tip of the first terminal 6 contacts the second terminal 7 is reduced.
- one end of the first terminal 6 extends toward the outside of the frame body 3 from one end of the second terminal 7, so that an external member is directed from the upper side of the first terminal 6 toward the first terminal 6. Even if a force acts in the direction from the first terminal 6 to the second terminal 7 due to the close contact, the possibility that the tip of the first terminal 6 contacts the second terminal 7 is suppressed.

- the tip of the first terminal 6 tends to come into contact with the second terminal 7 when it is bent or deformed in the direction of the second terminal 7 by the distance of. Therefore, when one end of the first terminal 6 extends toward the outside of the frame 3 rather than one end of the second terminal 7, a force acting in the direction from the first terminal 7 to the second terminal 8 is used. It becomes difficult for the first terminal 6 to contact the second terminal 7.
- the probe can be easily applied from above and below so as to sandwich one end of the first terminal 6 therebetween. Therefore, the continuity check of the first terminal 6 can be easily performed. If the second terminal 7 is longer than the first terminal 6, it is difficult to sandwich the first terminal 6 from above and below, and the second terminal 7 and the probe can easily come into contact with each other. Therefore, by making the first terminal 6 longer than the second terminal 7, the continuity check of the first terminal 6 can be facilitated.
- the first terminal 6 since the first terminal 6 is longer than the second terminal 7 and the third terminal 8, the first terminal 6 can be easily connected to the flexible substrate 10 which is easily bent.
- the first terminal 6 In order to connect the flexible substrate 10 and the input / output terminal 4 which are easily bent, the first terminal 6 is inserted into the conduction hole p1, and then the conduction holes p2 and p3 of the flexible substrate 10 which are bent are connected to the second terminal 7 and the third terminal. Align with the terminal 8. Then, each terminal can be connected to the flexible substrate 10 by inserting the second terminal 7 into the conduction hole p2 and further inserting the third terminal 8 into the conduction hole p3.
- the order in which the terminals are inserted into the flexible substrate 10 is the second terminal 7 or the third terminal 8 first. Positioning to insert the terminal into the conductive hole of the flexible substrate 10 that is easily deformed becomes difficult. Therefore, by making the first terminal 6 longer than the second terminal 7 and the third terminal 8, the first terminal 6 is first inserted into the conduction hole p1, and the conduction holes of the second terminal 7 and the third terminal 8 are inserted. Can be easily aligned.
- the vertical distance between the first terminal 6, the second terminal 7, and the third terminal 8 is provided so as to increase as the lengths of the first terminal 6, the second terminal 7, and the third terminal 8 become shorter. May be.
- the flexible substrate 10 positioned between the first terminal 6, the second terminal 7, and the third terminal 8 can be displaced as the distance between the first terminal 6, the second terminal 7, and the third terminal 8 increases. Becomes larger.
- the stress generated in the flexible substrate 10 due to the difference in length between the first terminal 6, the second terminal 7 and the third terminal 8 is the distance between the first terminal 6, the second terminal 7 and the third terminal 8. It is relieved by the displacement of the flexible substrate 10 which becomes larger according to the above. Therefore, the stress is suppressed from concentrating on a part of the flexible substrate 10.
