A terminal with a wire having a high sealing property, a manufacturing method thereof, and a wire harness are provided. The terminal with the wire includes an aluminum wire and a crimp terminal. A resin covering member is removed from the aluminum wire to form a conductor exposed portion (a wire forming process). The crimp terminal is connected to the conductor exposed portion to form a wire-terminal connection portion (a wire-terminal connection process). Then, an anticorrosion portion is formed such that a voltage is applied between the crimp terminal and a metal nozzle and an electrified anticorrosion material is supplied from the metal nozzle to the wire-terminal connection portion in a state of being attracted (an anticorrosion material supply process). Further, the anticorrosion portion is formed by irradiating the anticorrosion material with an ultraviolet ray to be UV-cured (an anticorrosion material curing process).
