A terminal-equipped electric wire includes: an electric wire including a core wire and an insulating coating; and a terminal connected to the core wire exposed from an end portion of the electric wire. The terminal includes: a flat-plate-shaped weld portion; a bottom plate portion; and a crimping piece. In a state where the crimping piece is crimped so as to be wound around an outer periphery of the insulating coating, a leading edge of the crimping piece is located on a bottom plate portion side with respect to a first virtual plane that passes through the center of the electric wire and is perpendicular to the bottom plate portion, and the leading edge of the crimping piece is in proximity to a side edge of the bottom plate portion on a side opposite to a side on which the crimping piece is provided.
