A wet-sheet laminated body includes multiple folded wet sheets that are stacked such that an end portion of one wet sheet among the wet sheets is sandwiched by a folded-back portion of another wet sheet among the wet sheets. Each of the wet sheets includes a base material sheet impregnated with a chemical solution such that impregnated portions that are impregnated with the chemical solution and non-impregnated portions that are not impregnated with the chemical solution are provided. The impregnated portions and the nonimpregnated portions are formed in a stripe pattern in which the impregnated portions and the non-impregnated portions are alternately arranged.
