A wire harness includes a plurality of cables arranged in parallel and a connector comprising a housing to which end portions of the plurality of cables are connected. The housing has an air-tight block at a side thereof that the plurality of cables are connected. The air-tight block further includes two closing parts for closing a space between the air-tight block and the cables at two places along a longitudinal direction of the cables, and for defining a part of a cable insertion hole. A metallic member protruding outwardly in a radial direction of the cables is fixed by swaging to a periphery of each of the cables between both of two closing parts for restricting a movement of the cables along the longitudinal direction in a pulling force or pressing force of the cables.
