摘要：
PROBLEM TO BE SOLVED: To suppress the temperature rise of a light emitting element and enhance the irradiation efficiency of ultraviolet rays to a fluid flowing in a flow path. A fluid sterilization apparatus according to an embodiment includes a tubular member, a base, a light emitting element, and a light source unit. The tubular member is open at both ends and allows a fluid to flow inside. The base has an accommodating portion that accommodates the tubular member, and a through hole that communicates with one end of the accommodating portion. The light emitting element is arranged so as to face the other end of the housing portion, and irradiates the housing portion with ultraviolet rays. The light source section has a peripheral wall protruding toward the housing section so as to cover the light emitting element from the fixed surface facing the housing section with the light emitting element interposed therebetween, and houses the light emitting element.
