The present invention relates to an ultraviolet sterilizer having an improved structure so that disassembly and assembly of each portion of the casing is improved, and an uneven portion is formed along the outer circumference of the casing to improve heat dissipation performance. In the ultraviolet sterilizer of the present invention, the seat plate 120, the lower plate 140 and the right plate 130 are integrally formed, and the upper plate 110 is the upper end of the seat 120 and the upper end of the right plate 130 The casing 100 is detachably coupled to the coupling means 400, the ultraviolet lamp 210 and the substrate 220 built in the casing 100, and a first connection means 500 on one side of the casing 100 ), a suction fan 310 and a suction filter 320 detachably coupled to the casing 100, and a discharge fan 330 and a discharge filter 340 detachably coupled to the other side of the casing 100 by a second connection means 600 ), and the upper and lower plate portions 110 and 140 and the seat plate portion 120 and the right plate portion 130 are composed of an uneven portion 150 formed in an uneven structure on each outer circumferential surface.
