Abstract
A water treatment device includes: a dual-pipe structure unit including an outer pipe, an inner pipe provided in the outer pipe, and a prevention member provided between the outer pipe and the inner pipe; and a light source unit radiating ultraviolet light in the axial direction to irradiate water subject to treatment flowing in the inner pipe. The inner pipe includes an opposing end facing the light source unit across a gap and an inflow end positioned opposite to the opposing end. The outer pipe includes an outflow port provided on an outer circumferential surface of the outer pipe. The water subject to treatment flowing out of the inner pipe via the gap flows out from the outflow port.
