A broadcast receiving apparatus having a seek function of sweeping a received frequency, stopping the sweeping if the level of the received signal is equal to or higher than a threshold level of an S meter signal in SD check (SD check results in H determination), and setting a reception state with the received frequency includes a signal meter configured to detect the level of the received signal, and an AGC circuit configured to control the level of the received signal with the field strength of an input signal. In this case, if the direct current value to be applied to the PIN diode is equal to or higher than a predetermined direct current value, the threshold level of the S meter signal is changed to a lower value under a state where the AGC circuit is operating because a neighboring interfering channel exists.
