<p>A water stopping structure includes a covered electric having a plurality of core wires covered with an insulation cover, and a core wire welding portion provided in a part of the covered electric wire where the insulation cover is removed and the core wires are exposed to the outside. In the core wire welding portion, the core wires are welded to each other. A gap between the core wires, which has a size capable of being filled up with a low viscosity water stop material by capillarity action, is formed in the core wire welding portion. The gap is filled up with the water stop material.</p> |
