<p>Provided is a capacitor module which does not consume power when the load on which the capacitor module is mounted is in a stand-by state in which the load is not running. A power source circuit (21) for controlling is in a conductive state while receiving a power-supply signal indicating that the load-side power source circuit (11) of a motor (15) which uses a capacitor module (1) as the power source is being supplied with power, and a power source switch circuit (29) electrically connects a capacitor unit (5) with the power source circuit (21) for controlling. When a power source switch (9) is turned on, power is not only supplied to the motor (15) from the capacitor unit (5) but is also supplied to a control substrate (7), and a control circuit (19) goes into an operation state. When the power source switch (9) is turned off, power is no longer supplied to the control substrate (7) and the control circuit (19) goes into a non-operation state. Therefore, it is possible to inhibit the consumption of power by the capacitor module (1) when a device (3) is in a non-operating stand-by state.</p> |
