Abstract
A fluid sterilization apparatus includes: a flow passage tube in which a processing passage where a passing fluid is sterilized is formed; a first light source that irradiates the processing passage with ultraviolet light; an inflow passage formed in a direction that intersects an outer circumferential surface of the flow passage tube; and a communication passage that causes the inflow passage to communicate with the processing passage. The communication passage has a narrow passage in the middle of a path from the inflow passage toward an opening of a first end, the narrow passage being narrower than a passage toward the inflow passage.

A fluid sterilization apparatus comprising:
- a flow passage tube in which a processing passage where a passing fluid is sterilized is formed;
- a light source that irradiates the processing passage with ultraviolet light;
- an inflow passage or an outflow passage formed in a direction that intersects an outer circumferential surface of the flow passage tube;
- and
- a communication passage that causes the inflow passage or the outflow passage to communicate with the processing passage, wherein
- the communication passage has a narrow passage in the middle of a path from the inflow passage or the outflow passage toward an opening of one end of the flow passage tube, the narrow passage being narrower than a passage toward the inflow passage or the outflow passage.

- an inflow passage or an outflow passage formed in a direction that intersects an outer circumferential surface of the flow passage tube;
- and
- a regulatory passage provided in an area facing an exit of the inflow passage or an entrance of the outflow passage and configured to change a flow of the fluid in a predetermined direction, wherein
- the regulatory passage has a curved passage leading from the exit of the inflow passage or the entrance of the outflow passage toward an end of the flow passage tube, and
- the regulatory passage has a narrow passage in the middle of a path from the inflow passage or the outflow passage toward one end of the flow passage tube, the narrow passage being narrower than a passage toward the inflow passage or the outflow passage.
