CORRUGATED TUBE AND WIRE HARNESS

A corrugated tube (1) includes a tube body (2) having a tubular shape and configured to accommodate an electric wire (W) inside, and a protection layer (3) laminated on the inner circumferential surface of the tube body (2). The tube body (2) has a bellows-shaped region having projections (2a) and recesses (2b) axially alternately continuous, and includes two circumferential ends (22a, 22b) circumferentially formed, and is circumferentially closed by the two circumferential ends (22a, 22b) facing each other. The protection layer (3) is laminated in end regions (23a, 23b) corresponding to the two circumferential ends (22a, 22b), respectively, of the inner circumferential surface, and has a hardness lower than the hardness of the tube body (2).
