To secure original transmission characteristics of a filter and to effectively use a mounting space by avoiding capacitance coupling between input/output terminals in the filter externally attached to an integrated circuit.
This television tuner is provided with a rectangular integrated circuit 10 comprised of two long sides 10a, 10b and two short sides 10c, 10d opposite to each other and a SAW filter 15 provided adjacent to the short side 10d of the integrated circuit 10 and arranged so that input terminals 24a, 24b may be located on the side of the long side 10a and output terminals 28a, 28b may be located on the side of the other long side 10b. IC output terminals 22a, 22b to be connected to the input terminals 24a, 24b of the SAW filter 15 are provided at a position at one long side 10a of the integrated circuit 10 near the SAW filter 15 and IC input terminals 26a, 26b to be connected to the output terminals 28a, 28b of the SAW filter 15 are provided on the other long side 10b of the integrated circuit 10 near the SAW filter 15.
