PROBLEM TO BE SOLVED: To provide a unit for suppressing sliminess by removing various germs, dirt, sliminess and odor produced inside of a bathtub after bathing. SOLUTION: A flange is attached to a plastic container which contains a copper plate worked in a bellows-state, and a lid of the same size is superposed. When the bellow-state copper plate contained in the plastic container is folded into the state of rectangular waves of 10 to 30 mm height and 2 to 3 mm width, the surface area of the copper plate in the same container is increased to be 1,000 cm<SP>2</SP>to 12,000 cm<SP>2</SP>. The apertures ratio of the plastic container is 30% to 80% so as to avoid hindering of flow/contact of bath water. Thus, in the plastic container containing the bellow state copper plate, the effect of deodorization and smliminess suppression by the disinfection effect of the copper plate is continued.
