PROBLEM TO BE SOLVED: To provide a television signal receiver that can eliminate the effect of reduction in a dynamic range of an intermediate frequency amplifier circuit and mutual interference between circuits or the like. SOLUTION: The television signal receiver is configured with an IC integrating a tuner circuit 10, a VIF amplifier 30, a video wave circuit 31 and an audio circuit 40 into a single chip. A pair of balanced outputs are adopted for the outputs of the tuner circuit 10. This pair of balanced outputs are outputted to IF output terminals 25, 26 and also fed to a pair of input terminals of the VIF amplifier 30 through a SAW filter 27 and IF input terminals 28, 29.
