What is necessary is just to bury this bare electric wire part 13 in the waterproof sealant 6,
It is not necessary to inject an adhesive between the electric wire of the lead wire and the insulating coating as in the related art, so that the workability at the time of production is greatly improved and the production cost is reduced. Furthermore, in the conventional case, usually, after soldering the tip of the lead wire, an adhesive is injected between the electric wire and the insulating coating, so that the adhesive penetrates between the electric wire and the insulating coating. It is difficult to reduce the reliability of the seal, but in the case of the present invention,
Since the middle part of the lead wire 9 that has not been soldered is sealed with the waterproof sealant 6, the waterproof sealant 6 easily penetrates between the electric wire 10 and the insulating coating 11, and the reliability of the seal increases.
