Abstract
A step-up circuit includes a transistor configured to perform switching operation in response to a pulse signal input into a base of the transistor, an inductor disposed between a collector of the transistor and a power source, and a basic step-up circuit connected to a connecting point of the collector of the transistor and the inductor. The basic step-up circuit includes: a first diode, a second diode whose anode is connected to a cathode of the first diode, a third diode whose anode is connected to a cathode of the second diode, a first capacitor disposed between the cathode of the first diode and ground, a second capacitor disposed between an anode of the first diode and the cathode of the second diode, and a third capacitor disposed between a cathode of the third diode and the ground.
