<p>PROBLEM TO BE SOLVED: To cause a metallic valve and an electric welding coupler to be posi tively and integrally assembled and further enable them to be endurable against a long term use by a method wherein a body of a metallic valve is integrally covered with a resin constituting the electric welding coupler. SOLUTION: A valve with electric welding coupler is made such that a resin constituting an electric welding coupler 3 and resin covering sections 2b, 2c of a body 2a of the metallic valve 2 are integrally formed, so that the coupler 3 and the metallic valve 2 are welded at wide area and welded in complex shape and even of they are used for a long period of time, inner fluid is not leaked out of a welding surface between the body 2a of the metallic valve 2 and the resin or the welding surface is not peeled off by a temperature or a pressure of the inner fluid, and the electric welding coupler 3 is not peeled off form the electrical welding coupler 3.</p> |
