Provided is an excimer lamp having a simple and small structure, which can be used in, for example, a refrigerator, and can emit ultraviolet light at a wavelength effective in disinfection processing without generating ozone in a surrounding atmosphere, without leaving gas impurities and moisture in an electrical discharge vessel, and without causing a steep illuminance decrease. A fluorescent substance is disposed on an inner face of the electrical discharge vessel for converting ultraviolet light emitted upon excimer electrical discharge of a light emitting gas to ultraviolet light having a longer wavelength. An inner electrode has a coil shape. A tight winding portion is formed at a certain area of the interior electrode which extends in the center axial direction of the interior electrode such that the coil is tightly wound in the tight winding portion. A getter is attached to the tight winding portion.
