An ultraviolet lamp is provided to improve an appearance by covering a contraction tube of both ends of a photo catalyst filter through a finish cap. A plurality of spacers(20) is arranged around an ultraviolet lamp(10). A through hole is formed in a center of the spacer. An external diameter of the spacer is larger than an external diameter of the ultraviolet lamp. A connection groove is formed on an outer circumference or an inner circumference of the spacer. The connection groove has a dove-tail shape. A photo catalyst filter(30) surrounds a plurality of spacers. A sterilization space(31) is formed between the ultraviolet lamp and an inner circumference of the photo catalyst filter. A contraction tube(40) is arranged in both ends of the photo catalyst filter. The contraction tube fixes the photo catalyst filter to ultraviolet lamp. A finish cap(50) covers the contraction tube in order to finish both ends of the ultraviolet lamp.
