To provide an electric welding joint stably holding a joining state by swaging between a terminal fitting and a resistant wire, certainly joining the terminal fitting and the resistant wire, and being manufactured at good yield, when a load is added on both end portion of the resistant wire in a direction coming out from a swaging portion of the terminal fitting due to fast flowing of resin at the time of injecting and filling a thermoplastic resin into a cavity under high pressure or shrinkage at the time of cooling and solidifying the resin.

This electric welding joint is provided with a joint main body 10, a resist wire 20, and a terminal fitting 30. The terminal fitting 30 is structured by using material having hardness same or not less than that of an inserting end portion 21 of the resistant wire 20.
