  • Publication number: 20240128733
    Abstract: An attachment structure of a flat wire harness includes: an attachment target member; a flat wire harness; and an attachment part. In the flat wire harness, a through hole is formed in a part of a base material where a plurality of electrical wires are not disposed. The attachment part includes a rod-like part passing through the through hole, a fixing part provided to a first end portion of the rod-like part to fix the rod-like part to the attachment target member, and a retaining part provided to a second end portion of the rod-like part to prevent the rod-like part from coming out of the through hole. An outer size of the retaining part is larger than a dimension of the through hole, and the dimension of the through hole is equal to or larger than a thickness of the rod-like part.
