CRYSTAL VIBRATION ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a crystal vibration element capable of reducing leakage of vibration energy to achieve a low crystal impedance (CI) value.SOLUTION: A crystal vibration element comprises: a tabular crystal piece 1; excitation electrodes 2 provided on both principal surfaces of the crystal piece; and routing pattern 3 that is provided at one edge of the crystal piece to connect to the excitation electrodes 2. The routing pattern includes: a pair of two connection pads 3a provided at an edge of the crystal piece, one of the two connection pads being thinner than the other; and a routing wiring 3b connecting the excitation electrode and the connection pad. The connection pads are provided in juxtaposition on one of the principal surfaces, and predetermined one of the two connection pad is only provided on the other principal surface and is thinner than the other connection pad.
