    • PURPOSE:To make collective molding of an insulating connection part formable stably by covering an edge-cut part with inner and outer external semiconductive layers and forming a tip part of the inner semiconductive layer to be not contractible or almost not contractible. CONSTITUTION:A conductor connection part 10 is covered with a reinforced insulation layer 16, and its outside is covered with an inner semiconductive layer 18 and an outer semiconductive layer 22, with an edge-cut insulation layer 20 in between. A tip part 32 of the inner semiconductive layer is made of a material which is not contractible or almost not contractible, and the other part is made of a heatcontractible material. The outer semiconductive layer 22 is also formed to be heat-contractible. The reinforced insulation layer 16 and the edge-cut insulation layer 20 are made of the same species or groups of materials, and they are closely adhered to each other. Since the tip part 32 is not almost deformed upon the collective molding formation of this insulating connection part, the part 32 does not penetrate into the reinforced insulation layer 16, and also continuous formation of the insulation layer is enabled collectively.
