PROBLEM TO BE SOLVED: To provide a sterilizer which is compact and has high sterilization performance.SOLUTION: A sterilizer 10 comprises: a channel 12 for circulating a fluid; a light source 30 for radiating ultraviolet light to the fluid in the channel 12; a heat sink 40 disposed so as to contact the fluid in the channel 12; and a heat pipe 34 for thermally connecting the light source 30 and the heat sink 40. The heat sink 40 may comprise plural projection parts 44 disposed so as to block a part of flowing of the fluid in the channel 12. The channel 12 may comprise a radiation chamber 20 where the ultraviolet light from the light source 30 is radiated. The heat sink 40 may be disposed on an upstream side of the radiation chamber 20 in the channel 12.SELECTED DRAWING: Figure 1 |
