A power circuit is provided which has a small peak value of a current from a power source even in the case of a load in which a load current repeats periodically and alternately a burst flow in a burst period and a non-burst flow in a non-burst period. The above power circuit includes a power source section (11), a power controlling suction (12), arid an energy storing section (13) having a storage capacitor (131) being connected to an output terminal. The power circuit is provided with a current controlling section (14) to control values of detecting resistors according to a result of detection of a voltage input from a power source section (11) and a control switching device (15) having a field effect transistor switch being connected between input and output terminals and a circuit made up of a capacitor (154) in which a flowing period of an output current is controlled by exerting the field effect transistor switch, (153) according to a control signal being produced by detecting a change in an input power voltage using a voltage occurring at another terminal of the detecting resistor.
