A wire harness includes conducting paths, a metal pipe into which the conducting paths are inserted, and a conducting path protective cap which includes a through hole for the conducting paths, and an engaging part which is engaged with a terminal part of the metal pipe. The terminal part of the metal pipe has a ring-like cap engagement space formed by crushing the terminal part towards a predetermined direction from a pipe outer surface of the metal pipe. The ring-like cap engagement space includes a reduced space and an enlarged space formed due to a crushing of the terminal part. The reduced part is formed by narrowing a part of a gap between the conducting paths and the pipe inner surface due to the crushing, and the enlarged space is formed by enlarging a part of the gap in accordance with a formation of the reduced space.
