摘要:
This invention relates to an acceleration sensor having less output drift due to temperature change and noise due to external induction which includes a piezoelectric device formed of a piezoelectric member having one or more electrodes provided on each of sides thereof and a lining member of low linear expansion coefficient adhered to one side thereof. A low linear expansion coefficient circuit substrate is provided having the piezoelectric device adhered to one side thereof and having a signal processing electronic circuit formed on the other side thereof. A cabinet having three layers, including an internal conductive resin layer, an adiabatic resin layer, and an external conductive metal layer, completely enclose the piezoelectric device and the circuit substrate.
