PROBLEM TO BE SOLVED: To provide a tablet-type cleaner capable of rapidly releasing active oxygen in a high concentration just after contact with water, and capable of successively releasing an active halogen in a low concentration over a long time after finishing the release of the active oxygen in the high concentration. SOLUTION: The tablet-type cleaner is obtained by pressurizing and molding at least one kind selected from a persulfate, a percarbonate and a perborate, and at least one selected from trichloroisocyanuric acid and a halogenated hydantoin compound without previously mixing them. The tablet-type cleaner is constituted of a layer containing at least one kind selected from the persulfate, the percarbonate and the perborate, and a layer containing at least one selected from the trichloroisocyanuric acid and the halogenated hydantoin compound.
