PROBLEM TO BE SOLVED: To provide a device for measuring temperature, for finding a temperature of a glass from a resistant value of a transparent conductive film provided adhered to a front glass. SOLUTION: The average temperature of the front glass 1 can be measured with high accuracy, in order to detect the temperature of the front glass 1 from the resistance value of the transparent conductive film 2 adhered to the front glass 1. Thus, heating operation of the wasteful front glass 1 can be suppressed, and power saving can be contrived. In addition, since the average temperature is detected within a range which arranges the transparent conductive film 2, measurement error is small, as compared with that of local detection. Furthermore, in order to measure the temperature of the front glass 1 with a means for heating the front glass 1, the cost required for a sensor can be suppressed. COPYRIGHT: (C)2004,JPO&NCIPI
