A diversity reception tuner of the invention has one first tuner and at least one tuner. The first tuner has a first PLL circuit and a first voltage-controlled oscillation circuit controlled by a tuning voltage generated by the first PLL circuit, and performs frequency conversion on a desired reception signal by using a local oscillation signal outputted from the first voltage-controlled oscillation circuit. The tuner performs frequency conversion on the desired reception signal by using the local oscillation signal outputted from the first voltage-controlled oscillation circuit. With this configuration, an inexpensive diversity reception tuner is realized that can always use the reception signal from whichever antenna offers optimum reception at the moment.
