To provide a connector device which includes a housing, has a structure reducing the size of the entire device and the number of components, and selectively operates a wiring plate member inserted into the housing between an engagement state and an engagement released state with easy operation.

An engagement part (25), which engages with a cutout engagement part in a flexible printed circuit board inserted into a housing (11) and forms an engagement state with the flexible printed circuit board, and an engagement releasing part (35), releasing the engagement state between the engagement part (25) and the flexible printed circuit board, are integrally formed with a conductive shell (14) partially covering the housing (11). The engagement releasing part (35) has an operation part (36) extending along a longitudinal direction of the housing (11).
