PROBLEM TO BE SOLVED: To provide a disinfecting device capable of efficiently disinfecting a hoof of an ungulate animal. SOLUTION: A disinfection device 1 has a rear nozzle 21 for a left front leg that injects a disinfectant solution from a rear position of a cow 2 toward a hoof 3 of the left front leg of the cow 2, and the cow 2 from a rear position of the cow 2. It is provided with a rear nozzle 22 for the right front leg that injects a disinfectant solution toward the hoof 3 of the right front leg. Further, the disinfecting device 1 includes a rear nozzle 23 for the left hind leg that injects a disinfectant solution from the rear position of the cow 2 toward the hoof 3 of the left hind leg of the cow 2, and the cow 2 from the rear position of the cow 2. It is provided with a rear nozzle 24 for the right hind leg that injects a disinfectant solution toward the hoof 3 of the right hind leg. These four rear nozzles 21, 22, 23, 24 are attached to one pipe 26 extending in the left-right direction.
