Abstract

PURPOSE:At least one side surface of a pair of surfaces which cross vertically in the thickness direction is formed in a taper shape, and one terminal section of the length direction is formed thick and the other terminal is formed thin respectively. The oscillator is supported via the thin terminal. As a result, a quartz crystal oscillator, which features reduced spurious oscillation and increased Q value and frequency stability, can be obtianed.
