A lock member has: a contact part that contacts one surface of an object to be connected; a locking part that has a shape allowing engagement with a part to be locked formed on the object to be connected; a connection part; and a pressure-receiving part that is pressed by a pressing member. The lock member includes at least one contact provided with a fixing function and used to enable electrification. The locking part projects in a direction that moves away from a board-mounting surface at a side near the board-mounting surface, at a position corresponding to the part to be locked of the object to be connected. The contact part is positioned on the side far from the board-mounting surface at the side facing the locking part, and at a position closer to an insertion side of the object to be connected than the locking part.

Connector

A connector includes a required number of contacts, an electrical insulation housing and a metallic shell. A tab is formed in the connector. A pressure receiving portion of the tab is pushed by a pushing portion of the shell to move the pressure receiving portion toward a mounting face of a substrate for applying a force in the insertion of FPC but not applying a force to the tab in the detaching thereof, whereby an engaging portion of the tab is moved in a direction opposing to the mounting face of the substrate to unfasten the engaging portion from an locking portion of the FPC.

A printed wiring board () includes: a base substrate (); a plurality of pads () for electrical connection that are disposed at one surface side of the base substrate () and at a connection end portion () to be connected with another electronic component (); wirings () that are connected with the pads (); and engageable parts () that are formed at side edge parts of the connection end portion () and are to be engaged with engagement parts () of the other electronic component () in the direction of disconnection. The flexible printed wiring board () further includes reinforcement layers () that are disposed at the other surface side of the base substrate () and at a frontward side with respect to the engageable parts () when viewed in the direction of connection with the other electronic component, and that are formed integrally with the wirings ().
