PROBLEM TO BE SOLVED: To provide an integrated circuit for a tuner wherein a reference oscillation signal appearing at a terminal connected to an oscillator hardly causes induction to other terminals. SOLUTION: A plurality of terminals respectively connected to mixer circuits 11, 12, an intermediate frequency amplifier circuit 20, oscillation circuits 13, 14, 15, a PLL circuit 17, and a reference oscillation circuit 19 are provided to opposed sides 10a, 10b of an integrated circuit 10. Among the terminals, at least an oscillator connection terminal No.7 for connecting the oscillator 27 placed at the outside of the integrated circuit 10 to the reference oscillation circuit 19, a power terminal No.8 to which power supply voltage is applied, and a ground terminal connected to ground are placed on the side 10a, and the power terminal No.8 and the ground terminal No.6 are placed adjacent to and on both sides of the oscillator connection terminal No.7.
