Grounding structure for shield wires

The invention realizes stable overall grounding. A portion of the grouping members (BW1 to BW3) of the shielded electric wires (1A, 1B, 1C) is led out to the outside to form drainage portions, and oneof them is used as a main drain portion (MD). A ground terminal (7) connected to a grounding point is attached to the tip of the main drain (MD). One ends of the relay wires (L1, L2) are connected tothe remaining drain portions (D1, D2), respectively, and the other ends of the respective relay wires (L1, L2) are connected to the ground terminals (7) collectively. 本发明实现稳定的总括接地。屏蔽电线(1A、1B、1C)的编组部件(BW1-BW3)的部分分别引出到外部从而形成排流部，并且将其中的个作为主排流部(MD)，在主排流部(MD)的顶端部安装有连接到接地点的接地端子(7)。在剩余的排流部(D1、D2)分别连接有中继电线(L1、L2)的端侧，各个中继电线(L1、L2)的另端侧并连接于接地端子(7)。
