Abstract

PURPOSE: To reduce the effect of leak resistance produced at detecting ends by providing an oscillator having operating characteristics that make electrostatic capacity approximately constant against the variation in leak resistance, thereby increasing the accuracy of detection of electrostatic capacity and making the size of the detecting device smaller.
