One embodiment of a tuner integrated circuit includes two mixer circuits, an IF amplifier circuit, three oscillation circuits, a PLL circuit, and a reference oscillation circuit. A plurality of terminals are provided at two sides of the tuner integrated circuit and are connected to these elements. Among the terminals, at least an oscillator-connecting terminal for connecting an externally provided oscillator to the reference oscillation circuit, a power supply terminal through which a power supply voltage is supplied, and a ground terminal connected to a ground are provided at one side of the tuner integrated circuit. The power supply terminal and the ground terminal are disposed adjacent to the oscillator-connecting terminal such that they sandwich the oscillator-connecting terminal therebetween.
