LIQUID CHEMICAL FEEDING DEVICE

PROBLEM TO BE SOLVED: To provide a liquid chemical feeding device capable of stably feeding a liquid chemical for a long period of time irrespective of a relationship between a water temperature and a room temperature.SOLUTION: The liquid chemical feeding device includes a liquid chemical container 2 and a substrate 3 on which the liquid chemical container 2 is removably mounted. The substrate 3 includes: a discharge member 42 connected to an exhaust port 20; and a liquid chemical feeding member 5' arranged opposite to the discharge member 42, and feeding the liquid chemical discharged from the liquid chemical container 2 into a stream of water at the time of flush. The liquid chemical feeding member 5' is equipped with a storage part 7 capable of storing water or the liquid chemical. The storage part 7 is constituted by a cylindrical body 70 provided so as to surround the lower end part of the discharge member 42, and the water or the liquid chemical can flow between the storage part 7 and the lower end part of the discharge member 42 via a groove 52.
