PURPOSE: To eliminate a disconnection of a soldered part by leaving a peeled part of a bundled core wire and reducing generation of stress of the core wire, when soldering the peeled tip of the core wire to a base or a lighting circuit component, as for a covered cord covered by a core wire with plural solid wires bundled. CONSTITUTION: A covered cord 30a is formed by using a core wire 31 with plural solid wires bundled, and therefore it is essentially softer than one using a core wire of a solid wire. In addition, since a peeled part 35 of the core wire 31 comprising the bundled wires is provided between the soldered part 34 of an eyelet terminal 3a and a covering 35, the peeled part can be easily transformed. Accordingly, since the peeled part 35 provided is soft, it is easily transformed, so that the covered cord 30 a transforms by following relative rotation displacement of a headlamp circuit part 11 and a base 3. Thereby, the covering can eliminate a disconnection of the soldered part by reducing generation of stress in the core wire. |
