PROBLEM TO BE SOLVED: To provide an electric current detection circuit capable of reducing loss in current detection circuit by reducing the current flowing through the current detection circuit, and using small-sized parts. SOLUTION: The circuit detects the current flowing by way of a capacitor C2 and a CR series circuit directly connecting a capacitor C3 and a resistor R1 to the capacitor C2 is connected in the constitution so that a current waveform is detected by measuring the voltage of a resistor RC2esr being parasitic on the capacitor C2.
