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.
