Further, as shown in FIG. 5A, in the FPC 110, the first straight line portion 111, the second straight line portion 112, and the connecting portion 113 are integrally formed in the substantially rectangular shape formed by the first state. ..
　また、図５Ａに示すように、ＦＰＣ１１０は、第１の状態において、連結部１１３から第１直線部１１１の先端の向いている方向（矢印Ａ）と、連結部１１３から第２直線部１１２の先端の向いている方向（矢印Ｂ）とが、略同じ方向である。 Further, as shown in FIG. 5A, in the first state, the FPC 110 is in the direction (arrow A) from the connecting portion 113 to the tip of the first straight line portion 111 and from the connecting portion 113 to the second straight line portion 112. The direction in which the tip is facing (arrow B) is substantially the same direction.
　図５Ａに示すように、ＦＰＣ１１０は、第１の状態において、長方形状を有する第１直線部１１１と第２直線部１１２とが、これらの短手方向に並べて設けられており、両者の境界に設けられた境界部Ｐ７において、両者は互いに切り離されている。 As shown in FIG. 5A, in the FPC 110, in the first state, the first straight line portion 111 and the second straight line portion 112 having a rectangular shape are provided side by side in the lateral direction thereof, and at the boundary between the two. At the provided boundary portion P7, the two are separated from each other.
　そして、ＦＰＣ１１０は、第１直線部１１１と第１屈曲シート部１１３Ａとの境界部Ｐ３と、第２直線部１１２と第２屈曲シート部１１３Ｂとの境界部Ｐ４とが、それぞれ山折りされる。 Then, in the FPC 110, the boundary portion P3 between the first straight line portion 111 and the first bent sheet portion 113A and the boundary portion P4 between the second straight line portion 112 and the second bent sheet portion 113B are mountain-folded, respectively.

The first bent sheet portion 117A is in a substantially vertical state when the boundary portion P9 with the second straight line portion 112 is mountain-folded. The second bent sheet portion 117B faces the first bent seat portion 117A at a predetermined relative angle θ in a plan view.
　接続部１１７Ｃは、第１屈曲シート部１１７Ａの下辺と第２屈曲シート部１１７Ｂの下辺（Ｚ軸負側の底辺）とを接続する略水平な底板状の部分である。 The connecting portion 117C is a substantially horizontal bottom plate-shaped portion that connects the lower side of the first bent seat portion 117A and the lower side of the second bent seat portion 117B (the bottom side on the negative side of the Z axis).
