To provide a connector device with a housing, which has a structure capable of reducing a whole height and decreasing the number of component members and can selectively set a wiring board-like member inserted in the housing in a locking state and a locking release state.

A locking mechanism (25) including: a locking part (27) for taking a locking state to a flexible printed wiring board (40) inserted in a housing (11); an operation part (26) for moving the locking part (27) in a direction isolated from the lower end surface part (11e) of the housing (11) and releasing a locking state to the flexible printed wiring board (40); and a coupling part (28) for coupling the locking part (27) to the operation part (26) is integrally provided in a shell member (14) partly covering the housing (11).
