PROBLEM TO BE SOLVED: To minimize a circuit of a push-push oscillator when it is used for various kinds of radio equipment, communication equipment and measuring instruments in high frequencies. SOLUTION: In the push-push oscillator constituted of capacitor 1 for resonance, a resonance circuit 3 to be constituted of a both-end open transmission line 2 connected with the capacitor 1 for resonance in parallel at both end parts and oscillating parts 4, 5 which are the same, symmetrical and operated in opposite phase to each other, the even-numbered harmonics output terminal 7 is connected with a midpoint of the both end open transmission line 2 via coupling capacity 10. Thus, the even-numbered harmonics output is taken out without using a combination circuit and minimization of the push-push oscillator is realized.
