Zusammenfassung:	Provided is a power tool capable of suppressing peak currents without increasing the size of the tool body. In an electric circular saw (100) provided with a motor (1), a rectifier circuit (91) configured to rectify AC voltage and output a rectified voltage; a smoothing circuit (92) configured to smooth the rectified voltage and output a smoothed voltage; and an inverter circuit (93) configured to supply the smoothed voltage to the motor (1) while performing switching actions with respect to the smoothed voltage, the smoothing circuit (92) includes a first capacitor and a second capacitor having different impedance and connected in parallel.
