A connection terminal includes a pair of connection portions interconnected through a fusion portion, and each of the connection portions is defined by a bottom plate, opposite side plates formed respectively on opposite sides of the bottom plate, and a top plate. A spring portion extending from the top plate is folded back from a front side thereof to be disposed within the connection portion so that a mating connection terminal can be held between the spring portion and the bottom plate. The connection terminal is stamped from an electrically-conductive metal sheet in such a manner that the spring portion extending from the top plate is extended along and disposed generally adjacent to the fusion portion before the spring portion is folded back.
