This inrush current suppression circuit suppresses an inrush current flowing to a load, and the load is provided with an input capacitor (10) connected to a power supply (1), and a pair of output terminals (3, 4), which are connected in parallel to the input capacitor (10), and which output a current inputted from the power supply (1). The inrush current suppression circuit is configured from: a FET (5) that is on/off controlled by being connected to the direct current power supply (1); a first inductor (8) connected between a connection point and the FET (5); a reflux diode (9) that connects the cathode to a connection point between the FET (5) and the first inductor (8); and a second inductor connected between the connection point and the anode of the diode. The first and second inductors (8) are configured from a magnetic body covering around an electric wire (L), i.e., a current path. |
