Abstract: A clip for a sheet electrode, which is capable of easily and reliably pinching a sheet electrode, and capable of minimizing the number of parts, thus facilitating the assembling. This clip is constructed such that a movable plate (20) provided with slots (25) to be engaged with supporting axes (13) is engaged with a substrate (10) having the supporting axes (13), and a conductive leaf spring (30) which is bent in the near middle thereof is interposed between the substrate and movable plate so as to keep them in an opened state. After the insertion of a sheet electrode (50), the movable plate is pivoted against the force of the leaf spring so as to close and pinch the sheet electrode. When the movable plate is further shifted forward along the slots, the movable plate is fixingly engaged with the substrate, thereby maintaining the pinching of the sheet electrode.
