PROBLEM TO BE SOLVED: To provide an injection synchronized oscillator that achieves high stability, a high multiplication degree and a small level of an undesired wave with a simple circuit configuration and small power consumption. SOLUTION: The injection locking synchronized is configured with a reference signal source with a frequency f/m (m is an integer of 2 or more), a coupling circuit that passes only the frequency f/m, and a series feedback type oscillation section. One end of a 1st transmission line is connected to the output terminal of the oscillation section, a signal trap with a frequency 2f and one end of a 2nd transmission line are connected to the other end of the 1st transmission line, and a signal trap with a frequency f and one end of an output circuit are connected to the other end of the 2nd transmission line.
