A method of manufacturing a terminal-equipped electrical wire includes: inserting a core-wire exposed part of a core wire of an electrical wire at a terminal between inner wall surfaces of a pair of piece parts of a terminal fitting including a core-wire connection body formed of a bottom part and the piece parts protruding from both ends of the bottom part, and placing the core-wire exposed part on an inner wall surface of the bottom part; melting the core-wire exposed part and the core-wire connection body by emitting a laser beam to the core-wire exposed part and the core-wire connection body from a free end side of each piece part; and fixing the core-wire exposed part and the core-wire connection body melted by the laser beam, with the emission of the laser beam stopped.
