To provide a manufacturing method of a wire with crimp terminal capable of preventing formation of an oxide film in a conductor consisting of a plurality of stranded core wires, while suppressing manufacturing cost.

The manufacturing method of a wire 1 with crimp terminal having a wire 10 formed by surrounding the outer periphery of a conductor 11 consisting of a plurality of stranded core wires 12 by an insulation coating 13, and a crimp terminal 20 being crimped to a conductor 11a exposed by stripping the insulation coating 13 of the terminal 10a of the wire 10 includes a terminal conductor exposure step for holding the insulation coating 13 of the terminal 10a having a cut formed in the circumferential direction so as to be drawn out from the conductor 11, and exposing the conductor 11 by pulling out the insulation coating 13 of the terminal 10a from the conductor 11 while rotating in the stranding direction of the plurality of stranded core wires 12, and a conductor compression step for compressing the exposed conductor 11a of the terminal 10a toward the radial center, after the terminal conductor exposure step.
