A connector capable of dispensing an actuator and reducing manufacturing costs. The connector includes a metal plate for sandwichingly supporting an FPC. The metal plate includes a first supporting portion mounted on a printed wiring board, and a second supporting portion connected to the first supporting portion via a linking portion in a manner movable in an FPC sandwiching direction. The second supporting portion includes a second movable portion opposed to the first supporting portion, and a second spring portion for causing the second movable portion to be urged against the inserted FPC. The second supporting portion includes a pair of locking pieces. The locking pieces cause the second movable portion to move away from the first supporting portion, using an FPC inserting force to increase distance between contact point portions of the first and second supporting portions, and prevent removal of the FPC.
