Disclosed a multi-output type DC/DC converter including: a reactor connected to a direct-current power supply; a first switching circuit composed of switches to apply a current to the reactor; a second switching circuit composed of switches to switch an output from the reactor to any one of output terminals; output voltage detection sections to detect voltages of the output terminals; comparison circuits to compare outputs with a waveform signal of a predetermined frequency; and an output selection circuit to receive inputs form comparison circuits, and to select an output of a comparison circuit, the output having the earliest rise or the earliest fall, so as to generate a control signal pertaining to on and off of the first and/or second switching circuit, wherein a current generated by a discharge of energy accumulated in the reactor is output to any one of the terminals in accordance with the control signal.
