Abstract: A contact includes a base portion, a cold-weld portion extending upward from the base portion and having a cold-weld slot into which an electric wire is configured to be cold-welded, a trailing portion extending downward by being folded back downward from an upper end of the cold-weld portion, and a contact portion extending from a lower end of the trailing portion. The trailing portion has a press-fitted portion below the cold-weld slot that is press-fitted into the housing. The contact portion makes contact with a mating contact by receiving the mating contact in a space between the contact portion and the base portion.
