Abstract: |
|||
| The invention provides a small crystal oscillating piece for requiring large driving power by reducing the amount of frequency variation by DLD, a crystal oscillator using the oscillating piece, and a crystal oscillating device with respect to a double rotation cut crystal oscillating member with thickness sliding oscillation as main oscillation. There are three crystal axes crossing with each other at right angles, namely, X axis is an electric axis, Y axis is mechanical axis which crosses the X axis, and Z axis is an optical axis which crosses the X axis and Y axis. In a crystal plate 10 for obtaining a crystal oscillation piece 20, X | |||
