Wire harness

A wire harness, comprising:

• an electric wire member including electric wires connected to each other, the electric wires each have a core wire covered by an insulation sheath;
• a cover member that covers a circumference of a connected part of the electric wires;
• a tubular member through which the electric wire member is inserted;
• and
• a tubular holder arranged at an end part of the tubular member and protecting the electric wire member at a part where the cover member is arranged, wherein
• the wire harness includes double-insulation portions where the core wire is covered by the insulation sheath and the cover member,
• the holder includes hollow portions at parts where the double-insulation portions are located,
• the electric wires include a first electric wire and a second electric wire that is connected to the first electric wire,
• the double-insulation portions include a first double-insulation portion where a first core wire of the first electric wire is covered by a first insulation sheath of the first electric wire and the cover member, and a second double-insulation portion where a second core wire of the second electric wire is covered by a second insulation sheath of the second electric wire and the cover member,
• the hollow portions include a first hollow portion formed at a part where the first double-insulation portion is located, and a second hollow portion formed at a part where the second double-insulation portion is located, and
• in the axial direction of the holder, the electric wire member is covered by the holder at one axial end side of the first hollow portion, between the first hollow portion and the second hollow portion, and at the opposite axial end side of the second hollow portion.
