An FM tuner capable of speeding up an AF search and a PTY search. A tuning operation by the FM tuner with an RDS demodulator is continuously controlled until a tuning is decided in accordance with a tuning signal outputted from a detector or a count of an intermediate frequency. The FM tuner has an AF search designating key for designating an AF search, a PTY designating key for designating a PTY search, and a changeover unit for switching to the tuning signal for the decision of a tuning when the AF or PTY search is designated.
