ーナ回路。[Claims for Utility Model Registration] In a tuning circuit that selects a desired tuning frequency by applying a reverse bias of a tuning voltage supplied from a tuning voltage supply terminal to a variable capacitance diode via a bias resistor, the bias resistor is the resistance of the tuning circuit. An electronic tuner circuit characterized in that the resistance value is selected to be approximately 15Ω or less, and by selecting this resistance value, a predetermined damping effect is obtained in the tuning circuit.
