いる。Industrial Applicability According to the present invention, a mesh-shaped metal resistor is sandwiched between polymerized portions existing at both ends of a thermoplastic resin sheet covering the outside of an object and connected to the mesh-shaped metal resistor. The mesh-shaped metal resistor is directly heated through a wire to melt the inner surface of the polymerized portion of the thermoplastic resin sheet. In this case, since the mesh-shaped metal resistor melts and bonds the polymerized portion in a state of being sunk in the thermoplastic resin sheet, the welded portion is reinforced. In addition, since the thermoplastic resin sheet can be uniformly melted by directly heating the mesh-shaped metal resistor itself, there is an advantage that even if the bonded portion is long, it can be bonded uniformly.
