A connector comprises a plurality of contacts which are formed using a plurality of conductive contact points provided on a first plate surface of an FPC as a connection object, a frame member which has an opening size and a height capable of receiving a mating connector and is attached to the first plate surface of the FPC so as to surround the contacts, and a plate-like member which is provided on a second plate surface of the FPC so as to extend over a region corresponding to the contacts. The frame member has locking holes which respectively engage with mating locking claws of the mating connector when the connector is fitted to the mating connector, thereby maintaining the fitting state of the connector and the mating connector.
