In a wet sheet, hydrophobic outer layer sheets are disposed on both sides of the hydrophilic inner layer sheet impregnated with cleaning solution. Each of intermediate layer sheets is folded over so as to form a space having an opening. End portions of the inner layer sheet are inserted into the spaces of the intermediate layer sheets. The inner layer sheet can come in contact with the outer layer sheet via a space between the intermediate layer sheets. With such a construction, sufficiently high frictional force acts between the inner layer sheet and the outer layer sheet.
