Abstract

　本発明は一面に開口する凹部と前記凹部を除く充実部が一体に形成された重り部と、前記凹部と前記充実部とが回動方向に沿って並ぶように前記重り部を回動自在に支持する１対のビーム部と、凹部が開口する前記一面と異なる他の一面において前記凹部と前記充実部とに跨って設けられた可動電極と、前記可動電極における前記凹部側と対向する位置に配設された第１の固定電極と、可動電極における前記充実部側と対向する位置に配設された第２の固定電極とから成るセンサ部を備え、１対の前記ビーム部を結ぶ直線を回動軸とした前記重り部の回動に伴う前記可動電極と前記固定電極との間の静電容量の変化から加速度を検出する加速度センサであって、前記重り部の重心位置から前記回動軸に下ろした垂線と前記可動電極の表面とが成す角度が略４５度となるように、前記ビーム部を前記凹部側にずらして配置したことを特徴とする加速度センサを提供する。
