Wire harness and method of manufacturing wire harness

A method of manufacturing a wire harness, comprising:

• an electric-wire first separation step of separating a plurality of electric wires along a stacking direction into a plurality of electric-wire layers by tearing off a second joint, performed on the plurality of electric wires in a state in which the plurality of electric wires each extending along an axial direction is aligned along a width direction intersecting with the axial direction and aligned in a multi-layered manner along the stacking direction intersecting with the axial direction and the width direction, a first joint joins a plurality of electric wires adjacent along the width direction to each other, and a second joint joins a plurality of electric wires adjacent along the stacking direction to each other;
• an electric-wire second separation step of separating, on a side of an end in the axial direction, at least one of the plurality of electric wires aligned along the width direction, which constitute the electric-wire layers, by tearing off the first joint of the electric-wire layers obtained by separation in the electric-wire first separation step;
• a terminal attaching step of attaching a terminal to the end in the axial direction of at least one of the plurality of electric wires separated in the electric-wire second separation step;
• and
• a terminal accommodating step of inserting the terminal attached in the terminal attaching step into a cavity of a connector.
