PROBLEM TO BE SOLVED: To provide a multiplication oscillator in which noise components lower than the n-th harmonic component are suppressed by promoting reduction in size. SOLUTION: In the multiplication oscillator where a multiplication circuit having a parallel resonance circuit and an amplification circuit grounded to earth potential is connected with an oscillation circuit, and the n-th harmonic component (n is an integer of 2 or above) of the oscillation circuit is outputted, the parallel resonance circuit comprises a series resonance circuit of an inductor and a capacitor having a resonance frequency lower than the n-th harmonic component, and a reactance element connected in parallel with the series resonance circuit.
