PROBLEM TO BE SOLVED: To provide an FPC (Flexible Printed Circuit) which prevents a contact failure caused by a glass fiber burr, etc., of a reinforcing plate laminated to a connector connecting portion, and prevents a circuit metal foil separation that is caused by the FPC connector connecting portion and a connector contacting piece sliding over each other when the connector connecting portion is inserted into a connector.;SOLUTION: An insulating base 1, the circuit metal foil 2, and a nickel-alloy plating 6 on a front end of the connector connecting portion 5 are integrated and bent toward the reinforcing plate 8 to form an eaves portion 5a. When the connector connecting portion 5 is inserted into the connector, the eaves portion 5a on the front end of the connector connecting portion 5 is formed as an eaves covering the reinforcing plate 8, so that a glass fiber burr, etc., of the reinforcing plate 8 hardly peels off and the connector connecting piece does not slide over the front end of the connector connecting portion 5. Consequently, a concern of separation of the circuit metal foil 2 from the insulating base 1 is eliminated. If an adhesive 7 is caused to stick out from an end of the reinforcing plate 8, an effect of preventing separation of a burr, etc., is further increased.;COPYRIGHT: (C)2010,JPO&INPIT
