Provided is a connector including a case having an opposing surface facing external device and a flat plate-shaped contact built in the case. The case includes a first opening which is formed at the opposing surface and through which a contact point of the contact to be connected to a connection terminal of the external device protrudes from the opposing surface, a receiver configured to receive a connector for external connection, and a holder configured to hold the contact. The contact includes the contact point which is disposed in the first opening and which is to contact with the connection terminal of the external device, an elastic portion which is disposed in the case and which moves the contact point in a substantially perpendicular direction relative to the opposing surface, a contact portion which is disposed in the receiver and which is to contact with a connection terminal of the connector for external connection, a held portion which is formed between the elastic portion and the contact portion and which is held by the holder in the case, and a connection portion which is formed between the elastic portion and the contact portion and which connects between the contact point and the contact portion in the case.
