Cable connection structure and cable arranging part

A cable arranging part of the present invention has a fixed shape and comprises a position determining portion, a plurality of cable through holes, and an opening. In a state in which the position determining portion is secured to a position reference portion, the cable arranging part is in a predetermined position on a substrate. The cable through holes become perpendicular to a line of the electrodes and parallel to the substrate in the predetermined position. The opening is provided somewhere midway through the cable through holes and a ground cable through hole. As for the sizes of the cable through holes in a perpendicular direction to the substrate in the predetermined position, the size of the cable through hole on the side where the electrodes are located relative to the opening is greater than the size of the cable through hole on the side opposite to the electrodes. 本发明的电缆设置部件将形状固定，具有位置决定部、多个电缆贯通孔、开口部。位置决定部在固定在位置基准部的状态时使电缆设置部件在基板上位于规定位置。电缆贯通孔在规定位置时与电极的列垂直且与基板平行。开口部设置在电缆贯通孔和接地电缆贯通孔的中途。就在规定位置时与基板垂直的方向
