To provide an anti-fogging device capable of determining fogging of window glass without use of a humidity sensor.SOLUTION: An anti-fogging device comprises a heater 11 for heating a vehicle window 1, which has a heating element 111 generating heat when carrying an electric current and being formed of a member in which electric resistance has correlation with humidity, and estimation parts 14 and 15 that estimate fogging of the window 1 on the basis of an electric resistance value by measuring the electric resistance of the heating element 111. For example, the heating element 111 is formed of a carbon nano-tube. For example, the heater 11 is arranged at a position corresponding to a field v1 of view of a camera 100, out of the window 1.SELECTED DRAWING: Figure 3

    【課題】湿度センサを用いることなく窓ガラスの曇りを判定可能な防曇装置を提供する。【解決手段】電流が流れると発熱し、電気抵抗が湿度と相関がある部材で形成された発熱体111を有し、車両の窓1を加熱するヒータ11と、発熱体111の電気抵抗を測定し、電気抵抗の値に基づいて窓1の曇りを推定する推定部14、15とを備える。例えば、発熱体111は、カーボンナノチューブで形成されている。例えば、ヒータ11は、窓1のうちカメラ100の視界v1に対応する位置に配置されている。【選択図】図3
