Abstract

　噴孔へ高圧燃料を流通させる高圧通路６ａｚ，６ｂｚ，６ｃｚを内部に形成するとともに、噴孔を開閉するようニードル（弁体）をさせるためのピエゾアクチュエータ２ｚ（駆動手段）等を収容するインジェクタボディー４ｚと、ボディー４ｚに取り付けられて高圧燃料の圧力を検出する燃圧センサ５０ｚと、燃圧センサ５０ｚからの圧力検出値を外部に出力するセンサ用端子５５ｚと、ピエゾアクチュエータ２ｚへの電力が供給される駆動用端子５６ｚと、センサ用端子５５ｚ及び駆動用端子５６ｚを保持するコネクタハウジング７０ｚと、を備える。そして、センサ用端子５５ｚ、駆動用端子５６ｚ及びコネクタハウジング７０ｚにより１つのコネクタを構成する。
