Abstract
A method of manufacturing an oscillator device having first and second oscillators being driven at first and second driving resonance frequencies gf1 and gf2, the method including a first step for processing the two oscillators, wherein, when the two oscillators are going to be processed as oscillators having first and second resonance frequencies different from the two driving resonance frequencies with a certain dispersion range, the two oscillators are so processed that the first and second resonance frequencies different from the two driving resonance frequencies become equal to first and second resonance frequencies f1 and f2, respectively, which are included in adjustable resonance frequency ranges, respectively, and a second step for adjusting the first and second resonance frequencies f1 and f2 so that they become equal to the first and second driving resonance frequencies gf1 and gf2, respectively.
