<p>The present invention provides a receiver that includes a plurality of tuners for receiving broadcasts such as satellite broadcast. A tuner circuit (1) includes an input terminal (11) for inputting a broadcast wave in which a video signal and/or an audio signal are modulated in a predetermined format, and a mount layer (13) on which a main circuit (12) for selecting, from the broadcast wave, a video signal and/or an audio signal included in a predetermined frequency band is mounted. In the tuner circuit (1), a first ground layer (15) is disposed, through a first dielectric layer (14), on the surface opposite to that on which the main circuit (12) of the mount layer (13) is arranged, and a second ground layer (17) is disposed through a second dielectric layer, thereby suppressing mutual interference between tuners.</p> |
