Claim:
A crimping device, comprising: a crimp indenter; a crimp anvil, wherein crimp pieces of a metal terminal and a conductor wire placed on an inner side of the crimp pieces are positioned between the crimp indenter and the crimp anvil, and wherein at least one of the crimp indenter and the crimp anvil is movable toward one another along a direction of a longitudinal center axis of the crimp indenter and the crimp anvil to crimp the crimp pieces of the metal terminal; at least two arch-shaped portions disposed on an inner surface of the crimp indenter, the at least two arch-shaped portions being adjacent to each other and symmetric with respect to the longitudinal center axis and originating at longitudinal guide walls of the inner surface of the crimping indenter; and a sharply pointed portion defined by curves of the at least two arch-shaped portions intersecting on the longitudinal center axis at center ends of the at least two arch-shaped portions, wherein each of the curves has a curvature set to be greater toward the sharply pointed portion than toward the longitudinal guide walls.
