摘要： A fluid sterilizer of an embodiment includes a processing chamber, a light source unit, and a supply flow path. The processing chamber processes a fluid. The light source unit has a light source, a cooling block, and a medium flow path. The light source irradiates the processing chamber with ultraviolet rays. The cooling block cools the light source. The medium flow path is provided inside the cooling block, and a cooling medium flows therein. The supply flow path connects the medium flow path and the processing chamber to each other, and supplies the cooling medium flowing through the medium flow path to the processing chamber as the fluid.
