A band switchable type tuning circuit has first switch means interposed between a power supply Vcc and an anode of a switch diode, a first resistor whose one end is connected to a cathode of the switch diode, second switch means interposed between the other end of the first resistor and a ground, a second resistor connected between the power supply Vcc and a connection point of the first resistor and the second switch means, and the third resistor connected between the ground and a connection point of the first switch means and the anode of the switch diode. The first switch means and the second switch means are turned on or off together by means of a band switching voltage.
