To provide an anti-fogging device for a vehicle which can remove fogging of a window while minimizing ventilation loss.SOLUTION: An anti-fogging device 10 which removes fogging of a front window 6 of a vehicle 5, comprises: an inside/outside switching door 31 which is capable of switching between air circulation in a cabin 7 or ambient air introduction to the cabin 7; a film heater 20 which heats the front window 6; a humidity sensor 40 which estimates a relative humidity of a surface on the cabin 7 side of the front window 6; and an ECU 50 which makes the film heater 20 generate heat and circulates air in the cabin by the inside/outside switching door 31 if the relative humidity is a first threshold value or more and less than a second threshold value, and makes the film heater 20 generate heat and introduces ambient air to the cabin 7 by the inside/outside switching door 31 if the relative humidity is the second threshold value or more.SELECTED DRAWING: Figure 1

    【課題】換気損失を最小限に抑えつつウィンドウの曇りを除去することができる車両用防曇装置を提供する。【解決手段】車両5のフロントウィンドウ6の曇りを除去する防曇装置10であって、車室内7の空気循環又は車室内7への外気導入を切替可能な内外切替ドア31と、フロントウィンドウ6を加熱するフィルムヒータ20と、フロントウィンドウ6の車室内7側の表面の相対湿度を推定する湿度センサ40と、相対湿度が第1閾値以上かつ第2閾値未満の場合にはフィルムヒータ20を発熱させると共に内外切替ドア31によって車室内の空気を循環させ、相対湿度が第2閾値以上の場合にはフィルムヒータ20を発熱させると共に内外切替ドア31によって車室内7へ外気を導入するECU50と、を備える。【選択図】図1
