In an input tuning circuit, during reception of a television signal in the UHF band, a second tuning circuit unit is tuned to the UHF band by turning on a first switching diode, and a first tuning circuit unit is made to operate as a trap circuit in a frequency range lower than the UHF band by turning on a second switching diode. As a result, the transmission characteristics of the second tuning circuit unit become narrow and interference characteristics are improved. In addition, since a dedicated trap circuit need not be separately provided, an increase in cost is limited to a minimum and an increase in size is prevented.
