WIPO Patent Application WO/2012/157501
Kind Code:
A1
Abstract:
[Problem] To provide a metal joint part having improved electrical characteristics and mechanical strength. [Solution] A center caulking portion (2) is formed by putting metal plates (10, 11) on top of each other, cutting the metal plates (10, 11) along first to fourth cutting lines (L1 to L4), and pressing a portion surrounded by the first to fourth cutting lines (L1 to L4) to dent the portion. Since the portion is dented while cut sections along the first to fourth cutting lines (L1 to L4) rub each other, metal joint portions are formed on the cut sections along the first to fourth cutting lines (L1 to L4).
