- the tear line 145 is also a perforation 145 in this example.
- the through hole 47 is larger than each cut 46 forming the perforations 145 .
- the through hole 47 is formed in a circular shape. This prevents the sheet 140 from being torn across the other end of the tear line 45 .

- the tear line 245 is torn up to the through hole 47 in the intermediate portion, and the sheet portion 250A1 is folded back to form the folded portion 54. At this time, even when the tear line 45 is torn to the intermediate portion, the amount of tearing can be made constant by the presence of the through hole 47 .
- a tear line 245 remains between the intermediate through-hole 47 and the other end of the tear line 245 . Even in this case, the presence of the through hole 47 in the intermediate portion prevents the remaining tear line 245 from being torn starting from the torn portion.

以下、実施形態1にかかる配線部材について説明する。図1は実施形態1にかかる配線部材10を示す概略平面図である。図2は図1の部分拡大図である。
上記配線部材10を用いた複数の品番へ対応について説明する。
第1の品番は、図2に示すように、折り返されていない配線部材10Nである。配線部材10Nにおいて、引裂線45は裂かれていない。配線部材10Nにおいて、裂かれて分かれたシート部分が折り返しできない程度に引裂線45は裂かれていてもよい。配線部材10Nにおけるコネクタ20A、20Bの相手側コネクタ80A、80Bは、共に第1端部41の外側に位置する。
