Provided are a wire harness and a connector (40) allowing a routing path for an electrical wire (100) to be set without increasing the number of components and without requiring a complicated operation. A plurality of connectors (40) are aligned in a direction intersecting a front-rear direction. Each connector (40) is provided with a housing (41) capable of being fitted into a counterpart housing (71). The front face of the housing (41) is oriented in the direction facing the counterpart housing (71) at fitting both the housings (41, 71). The housing (41) is provided with a plurality of through portions (52A, 52B) passing through the housing (41) in the direction intersecting the front-rear direction. Each of the plurality of through portions (52A, 52B) has a space capable of routing an electrical wire (100) extended out from each connector (40).
