ABSTRACT:
Crimp pieces (21) of a metal terminal and a conductor wire placed on an inner side of the crimp pieces are positioned between a crimp indenter (11) and a crimp anvil (18). Then, at least one of the crimp indenter (11) and the crimp anvil (18) is moved toward another one thereof along a direction of a longitudinal center axis (12) to crimp the crimp pieces (21). At least two arch-shaped portions (13) are disposed on an inner surface of the crimp indenter (11), and are adjacent to each other and symmetric with respect to a plane including the longitudinal center axis (12). A sharply pointed portion (14) is defined by curves of the at least two arch-shaped portions (13) intersecting on the longitudinal center axis (12). Curvature of each of the curves is set to be greater toward the sharply pointed portion (14).
