An in-vehicle backup the control apparatus includes a switch unit (for example, including second switch units), a control unit, a low-voltage detection circuit, and a latching circuit. The switch unit is provided between a power storage unit and a load (for example, a second load). The control unit controls the switch unit. The low-voltage detection circuit detects a low-voltage state of an electric power path through which electric power from a power supply unit is supplied. When the low-voltage detection circuit detects the low-voltage state, the latching circuit is switched to a latched state in which the switch unit is kept in an on state. When the electric power path is in the low-voltage state, the control unit releases the latched state and controls the switch unit to be in an on state.
