A method of manufacturing a terminal-attached electric wire includes: installing an electric wire including a core wire including a plurality of element wires to a terminal having a conductor coupling part having a pair of barrel pieces, the core wire being installed between the pair of barrel pieces; bending the pair of barrel pieces to cause the pair of barrel pieces to wrap around and cover the core wire in a circumferential direction to form a slit extending in an axial direction between the pair of barrel pieces, with respect to the circumferential direction; melting the element wires of the core wire by emitting laser light toward the core wire through the slit; and adhering the element wires melted with the laser light to the conductor coupling part.

It is aimed to provide a ground terminal fitting suitably connectable to each of various wires. A ground terminal fitting includes a bolt fastening portion (10) to be bolted to a ground part and a wire connecting portion (20) to be connected to an end part of a wire (30). The bolt fastening portion (10) and the wire connecting portion (20) are coupled after being separately formed. According to this configuration, since the wire connecting portion (20) can be formed of an optimal material into an optimal shape, the wire connecting portion can be suitably connected to each of various wires (30).
