ABSTRACT:
An incandescent lamp has a bulb with a built-in filament therein, and an infrared ray reflection film formed on one or both of the outer and inner surfaces of the bulb and containing a non-crystalline metal oxide. The infrared ray reflection film is excellent in transmittance of visible rays and in reflectance of infrared rays and does not cause separation.
