Abstract: Even in the case of a bar-like small terminal connection, its strength is retained. In (a), a strip (21) made, for example, of a thin metal sheet having a thickness of 0.2 mm and a predetermined width is collapsed by rolling to a thickness of 0.16 mm as in (b). Subsequently, as in (c), the longitudinal opposite sides (22, 23) of the strip (21) are erected with respect to the base plate (24), then inwardly bent, as in (d), and folded onto the base (24), as in (e). Further, the folded opposite sides (22, 23) are erected together with the base plate (24) into a closely contacted state, whereupon as in (f), the folded body is mechanically compressed from all sides into a form having a 0.64-mm square cross section.
