【0010】 本発明に係る圧力センサによれば、放電経路が、センサチップの信号処理電子回路を迂回して形成され、電位調整部材に接続される入出力端子群の一部を構成する接地用端子または電位調整部材からの静電気を導電性ハウジングに対し放電する放電部を介してアースに逃がすことにより、センサチップの内部回路に悪影響を及ぼさないように、静電気放電に起因した放電電流を大幅に除去できる。

Abstract
To be able to largely remove discharge current caused by electrostatic discharge so as not to adversely affect an internal circuit of a sensor chip, in a pressure sensor.SOLUTION: Distance (insulation distance) Da between a shield plate of a potential adjusting member 17 and a diaphragm 32 is set to be separated by a predetermined insulation distance, and minimum insulation distance Da is, for example, set so that static electricity is discharged from the shield plate to the diaphragm 32 under a predetermined withstand voltage.SELECTED DRAWING: Figure 1
