A connecting terminal has a rectangular tube-like connecting portion including a bottom plate 13, a first side plate 14, a top plate not shown and a second side plate not shown, a movable contact strip 20 is secured to the bottom plate 13 at a base portion 20a, said movable contact strip 13 being further bent into a shape of mountain such that an apex of the mountain constitutes a contact portion 20d. Prior to the formation of the connecting portion, the movable contact strip 13 is folded over the bottom plate 13. An elongated strip portion of the bottom plate 13 is cut and bent inwardly to form a reinforcing strip not shown. A rear end of the movable contact strip is connected to the bottom plate 13 and a free front end of the reinforcing strip is urged against a lower surface of the contact portion 20d of the movable contact strip 20. At a front end of the connecting portion 11, a guide strip 22 is formed by folding back a front end portion of the bottom plate 13 such that the guide strip 22 covers the free front end 20c of the movable contact strip 20 to prevent an upward movement of the free front end 20c and to guide a corresponding male type connecting terminal.
