PROBLEM TO BE SOLVED: To provide a television broadcast receiver which is the television broadcast receiver with a digital tuner, and is improved in cost reduction by miniaturization of a digital signal processing substrate, and reduction of effect to an analog signal system of noise occurred in a digital signal system. SOLUTION: Miniaturization of the digital signal processing substrate 31 is made possible, and simultaneously effect of noise occurred on the digital signal processing board 31 is suppressed to effect to an analog signal system of a digital/analog shared tuner 323 by installing the digital/analog tuner 323 with a SAW filter circuit and an IF amplifier circuit on an analog signal processing board 32, and adopting a construction to mount a digital demodulation unit 111 on a digital signal processing board 31.
