Electric wire holding member and wire harness

A wire harness comprising:

• an electric wire holding member including a main body portion that is formed in a cylindrical shape having a central axis line as an axial center and includes an outer peripheral surface about the central axis line;
• a plurality of electric wire accommodating portions that are provided to penetrate through the main body portion along the central axis line, respectively, and are formed to be capable of individually accommodating electric wires, respectively, the plurality of electric wire accommodating portions being disposed along a circumferential direction around the central axis line at equal intervals in a cross section as viewed from an axial direction along the central axis line;
• a space portion that is a void formed in a gap between two electric wire accommodating portions adjacent to each other along the circumferential direction out of the plurality of electric wire accommodating portions to penetrate through the main body portion along the central axis line;
• and
• at least two outer edge portions erected from opposite ends of a cylindrical outer peripheral surface of the main body portion and formed to extend along the circumferential direction, wherein the space portion radially extends to a back of the outer peripheral surface through a gap between the adjacent electric wire accommodating portions from the central axis line and is closed by the outer peripheral surface,
• an electric wire portion in which three or more electric wires are gathered in the same direction and an arrangement of each electric wire of the electric wire portion around the central axis line is maintained by the electric wire holding member,
• a tape that is wound onto the outer peripheral surface of the main body portion so that the electric wires of the electric wire portion are fixed to the electric wire holding member, and
• a protective member that covers an outer peripheral side of the electric wire holding member in a state the electric wires of the electric wire portion are fixed to electric wire holding member by the tape.
