A connector for a flat cable connecting a connection terminal part of a flat cable to an electronic device includes a housing, a terminal, and a lock member. The housing is fixed to the electronic device and is formed with an insertion part into which a flat cable is inserted and a flat cable accommodation space that continues from the insertion part to an inside of the housing. The terminal is aligned and disposed in the housing, is connected to a wiring terminal provided to the electronic device and is contact-connected to the connection terminal part of the flat cable when the flat cable is inserted into the flat cable accommodation space. The lock member is put on a backside of a surface of the housing facing the electronic device and is formed with a pair of flat cable holding parts engageable with locking holes.
