There has been a problem of generating anti-resonance between a three-terminal capacitor and a capacitor when the three-terminal capacitor and the capacitor are mounted. In order to solve the problem, this electronic circuit includes: a capacitor and a three-terminal capacitor, which are connected to a power supply terminal of a circuit component, and a power supply, and which are connected in parallel to each other between the power supply and ground; and a resistor that is connected in series between the ground and a ground terminal of the three-terminal capacitor and/or the capacitor.
