Summary:To provide an electrode expansion type electrostatic capacitive sensor with an increased design freedom in a detection region.SOLUTION: The electrostatic capacitive sensor according to the present invention is a sensor in which an electrostatic capacitive value is changed according to the approach of a detection target. The sensor includes: an electrostatic capacitive sensor part forming an electrostatic capacity; and a conductive expansion electrode not connected to the ground, the expansion electrode being located at least partially in an initial detection region of the electrostatic capacitive sensor part.SELECTED DRAWING: Figure 2 【課題】従来よりも検出領域の設計自由度を向上させた電極拡張型静電容量式センサを提供すること。【解決手段】本発明に係る静電容量式センサは、被検出対象の接近に応じて静電容量値が変化する静電容量式センサであって、静電容量を形成する静電容量式センサ部と、グラウンドに接地接続されておらず、導電性を有する拡張電極と、を備え、前記拡張電極は、前記静電容量式センサ部の初期検出領域内に少なくとも一部が存在するように配置されていることを特徴とする。【選択図】図２
