Fluid sterilization device

Abstract

A fluid sterilization device includes: a sterilization chamber body that includes a sterilization chamber for a fluid, a wall surface of which being formed in a concave spherical shape, the sterilization chamber body being formed such that a light source opening, a chamber inlet that allows the fluid to flow into the sterilization chamber, and a chamber outlet that allows the fluid to flow out of the sterilization chamber are formed to open into the sterilization chamber; and a light source unit configured to close the light source opening and emit ultraviolet light from the light source opening into the sterilization chamber. The light source unit includes a light-emitting element that emits ultraviolet light, and the light source opening is formed such that an edge line of the light source opening is included in a region that constitutes −10° to +10° around a half-value angle the light-emitting element.
