PRESSURE SENSOR

To provide a pressure sensor capable of suppressing an influence of noise to a pressure detection device as much as possible.SOLUTION: In a pressure sensor having a pressure detection unit, a connector, and a junction board, the junction board includes a power wiring pattern in which a terminal pin for supplying power and a connector pin are connected, a signal wiring pattern in which a signal output terminal pin and a connector pin are connected, and a ground pattern in which a ground terminal pin and a connector pin are grounded. The signal wiring pattern has a near side wiring part extending along an edge of the ground pattern, a far side wiring part extending along the near side wiring part in a side opposite to the ground pattern while sandwiching the near side wiring part, and a middle wiring part for connecting one end of the near side wiring pattern and one end of the far side wiring part. The other end of the near side wiring part is connected to the connector pin for outputting signals, and the other end of the far side wiring part is connected to the terminal pin for outputting signals.SELECTED DRAWING: Figure 2 【課題】圧力検出装置に対するノイズの影響を極力抑制できる圧力センサを提供する。【解決手段】圧力検出ユニット、コネクタ、及び中継基板を有する圧力センサにおいて、前記中継基板は、電力供給用の端子ピンとコネクタピンとが接続される電力用配線パターン、信号出力用の端子ピンとコネクタピンとが接続される信号用配線パターン、及びアース用の端子ピンとコネクタピンとが接地されるグラウンドパターンを有し、前記信号用配線パターンは、前記グラウンドパターンの縁に沿って延在する近側配線部、前記近側配線部を挟んで前記グラウンドパターンと反対側において前記近側配線部に沿って延在する遠側配線部、及び前記近側配線部の一端と前記遠側配線部の一端とをつなぐ中間配線部を有し、前記近側配線部の他端と、信号出力用の前記コネクタピンとが接続され、前記遠側配線部の他端と、信号出力用の前記端子ピンとが接続される。【選択図】図２
