PROBLEM TO BE SOLVED: To provide an intermediate frequency output circuit capable of utilizing inexpensive transistors with a small rated power and eliminating the need for taking into consideration heat dissipation. SOLUTION: The intermediate frequency output circuit includes an emitter follower circuit 4 comprising a plurality of transistors 4a, 4b connected in parallel and to bases of which an intermediate frequency signal is given, the emitters of the transistors 4a, 4b are connected to ground via a common emitter bias resistor 4e, a feedback resistor 4c (4d) is interposed between the emitter bias resistor 4e and the emitter of the transistor 4a (4b), and each emitter outputs the intermediate frequency signal.
