Abstract
The present invention provides a receiver that includes a plurality of tuners for receiving broadcasts such as satellite broadcast. A tuner circuit () includes an input terminal () 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 () on which a main circuit () 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 (), a first ground layer () is disposed, through a first dielectric layer (), on the surface opposite to that on which the main circuit () of the mount layer () is arranged, and a second ground layer () is disposed through a second dielectric layer, thereby suppressing mutual interference between tuners.
