PROBLEM TO BE SOLVED: To provide a water treatment device using ultraviolet light with ozone which enables the compactification of a system and can decompose hardly decomposable organic substances and the like while suppressing a water treatment cost. SOLUTION: The water treatment device using ultraviolet light with ozone comprises an outer vessel 2 for water treatment, an inner vessel 3 disposed in the outer vessel 2, an ultraviolet lamp 6 disposed in the inner vessel 3, a suction pipe 7 of which one end communicates with and is connected to a space 4 for ozone generation between the inner vessel and the ultraviolet lamp, and of which the other end communicates with and is connected to a space 5 for passing water between the outer and inner vessels, and an air feeder 8 for supplying a gas in the suction pipe 7 toward the space 5 side for passing water from the space 4 side for ozone generation.
