A tuner for both digital and analog use that can receive both digital broadcast and analog broadcast signals, includes a signal input terminal; a frequency conversion section which converts and inputted signal to an IF signal; and a switching/distributing section which, based on the type of received signal (analog/digital), switches a destination to which to send the IF signal or distributes the IF signal. There is also a down-converter section, that further converts the IF signal into a Low IF signal; a terminal for output of the IF signal. The aforementioned components are all contained in a single body that performs an electromagnetic seal function. Operation of the switching/distributing section and/or the down-converter section may be controlled by a control signal from a structural element within the body.
