PROBLEM TO BE SOLVED: To provide a method for determining a driver's carelessness and a determination device therefor.SOLUTION: The method for determining a driver's carelessness according to the present invention includes: a step in which an object body with an impedance component is sensed by an electrostatic sensor provided to a headrest of a vehicle seat; a step in which a change in electrostatic capacity is sensed by the electrostatic sensor; a step in which a distance value between the object body with an impedance component and one or more of the electrostatic sensors is measured using the change in electrostatic capacity sensed by the electrostatic sensor; and a step in which it is determined whether or not the object body with an impedance component is in a state of carelessness using the distance value. 【課題】運転者不注意判断方法及びそのための判断装置を提供する。【解決手段】本発明による運転者不注意判断方法は、車両座席のヘッドレストに設けられた静電センサによってインピーダンス成分を持つ対象体が感知される段階と、静電センサによって静電容量の変化が感知される段階と、静電センサが感知した静電容量の変化を用いてインピーダンス成分を持つ対象体と１つ以上の静電センサとの間の距離値が測定される段階と、距離値を用いてインピーダンス成分を持つ対象体が不注意状態であるか否かが判断される段階と、を含むことを特徴とする。【選択図】図１５
