This voltage detecting circuit is provided with: an amplifier, which has an inverting input terminal and a non-inverting input terminal, and which amplifies a voltage difference between a first input signal inputted to the non-inverting input terminal via a first input section, and a second input signal inputted to the inverting input terminal via a second input section; a first signal line that connects the first input section and the amplifier to each other; a second signal line that connects the second input section and the amplifier to each other; a first capacitor connected in parallel to the first signal line; a second capacitor connected in parallel to the second signal line; a first filter element, which has an inductor component and a resistance component, and which is connected in series to qthe first signal line between the first capacitor and the amplifier; and a second filter element, which has an inductor component and a resistance component, and which is connected in series to the second signal line between the second capacitor and the amplifier. |
