Abstract: A relay control apparatus includes a relay contact, a relay coil which turns on the relay contact when the relay coil is electrically conducted, and a current control unit which controls a first current and a second current. The first current is larger in a current amount per unit time than the second current. The current control unit controls to flow the first current through the relay coil until a predetermined time has elapsed from a beginning of an electrical conduction of the relay coil. The current control unit controls to start to flow the second current through the relay coil on or before the predetermined time has elapsed to maintain a turn-on state of the relay contact. The predetermined time is longer than a chattering time in which a chattering in the relay contact occurs at the beginning of the electrical conduction.
