JOINTED METAL BODY, METAL JOINTING METHOD AND METAL JOINTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a jointed metal body showing an improved electric characteristic and reliability, a metal jointing method and a metal jointing device.

SOLUTION: Protrusions 12 and 13 protruding in a pressing direction Y1 are formed by cutting two metal plates 10 and 11 along a cut line extending from one end of a non-cut line through a side apart from the non-cut line to the other end of the non-cut line with the two metal plates 10 and 11 superimposed on each other, and by pressing a portion enclosed by the cut line and the non-cut line of the two metal plates 10 and 11. The metal jointed part is formed between the cut outer circumferential surface of the protrusion 12 of the metal plate 10 located on the reverse side of the pressing direction Y1 and the cut inner circumferential surface of a hole 15 of the metal plate 11 located on the pressing direction Y1 side.
