ABSTRACT:
A temperature detecting unit including a temperature detecting sensor, a window member, and a frame which holds the window member. The temperature detecting sensor receives infrared rays radiated by an object, thereby detecting the temperature of the object without contact with the object. The window member is arranged between the object and the temperature detecting sensor, and transmits the infrared rays. The window member includes a surface with a fluorination organic compound.
