PROBLEM TO BE SOLVED: To provide a chemical feeding device capable of preventing chemical- dissolved water from flowing into a hand-wash part and preventing the chemical- dissolved water from oozing to the outside through a joint between an upper cover and a tank main body. SOLUTION: This chemical feeding device for water closet comprises a lower member 3 and an upper member 2. The upper member 2 assures a chemical storage space and is fitted to the lower member 3. A part of hand-washing water is taken in from a groove 231 in a flow-in part 23, chemical is dissolved in the water, and the water is discharged from a discharge port 33. The length of the discharge port 33 is set longer than the length of a discharge hole in a hand-wash part. Also, a plurality of erected pieces are disposed and formed on the inner surface of the lower member 3 so as to be formed spirally about the discharge port 33 as viewed in horizontal plane.
