A connector is electrically connected to a substrate in which a conductor pattern and electrodes at ends of the conductor pattern are provided on a surface of the substrate. The connector includes a plurality of contacts that are resiliently connectable to the electrodes of the substrate inserted in the connector. An insulator member contains the contacts arrayed therein. A slider unit is movably attached to the insulator member, the slider unit including a plurality of lugs that are connectable to respective edges of the contacts contained in the insulator member. The connector is configured such that the respective edges of the contacts are connected to the lugs of the slider unit before the slider unit is moved relative to the insulator member, so as to separate the contacts from the electrodes of the substrate, and the respective edges of the contacts are disconnected from the lugs after the slider unit is moved relative to the insulator member, so that the contacts are resiliently connected to the electrodes of the substrate.
