An FM detector circuit includes an unbalanced/balanced conversion circuit (2), a signal synthesis circuit (3), a parallel circuit including a first diode (D1) connected between a first balanced output terminal of the unbalanced/balanced conversion circuit (2) and one signal input terminal of the signal synthesis circuit (3) and a resonator (X1), a parallel circuit including a second diode (D2) connected between a second balanced output terminal of the unbalanced/balanced conversion circuit (2) and the other signal input terminal of the signal synthesis circuit (3) and a capacitor element (C1), and a low-pass filter (4) connected to an output terminal of the signal synthesis circuit (3).
