To provide a vehicular mirror which suppresses discomfort related to visibility imparting to a driver in relation to the vehicular mirror which utilizes liquid crystal.SOLUTION: A vehicular mirror includes a mirror part 30 capable of regulating reflectance with a voltage applied to a liquid crystal layer 32A and a control part (control substrate 22) which performs anti-glare control for adjusting reflectance by controlling a voltage applied to the liquid crystal layer 32A. Therein, the control part (control substrate 22) performs calculation processing for determining a target voltage to be applied onto the liquid crystal layer 32A based on dazzling light and voltage regulating processing for causing the voltage to be applied to the crystal layer to arrive at the target voltage while increasing or decreasing the voltage by dividing the voltage to be applied to the liquid layer by a plurality of times when the voltage to be applied to the liquid crystal layer is different from the target voltage.SELECTED DRAWING: Figure 2

    【課題】液晶を利用した車両用ミラーであって、運転者に与える見え方に関する違和感を抑制した車両用ミラーを提供する。【解決手段】本発明の車両用ミラーは、液晶層32Aに印加する電圧で反射率を調整できるミラー部30と、液晶層32Aに印加する電圧を制御して反射率を調整する防眩制御を行う制御部(制御基板22)と、を備え、制御部(制御基板22)が、眩光に基づいて液晶層32Aに印加する目標電圧を求める演算処理と、液晶層に印加している電圧が目標電圧と異なっている場合に、液晶層に印加する電圧を複数回に分けて増加又は減少させて目標電圧に到達させる電圧調整処理と、を含む処理を実行して防眩制御を行う。【選択図】図2
