PURPOSE: To effectively attain the purpose of moisture holding in regardless of shape and size of the nose by providing a honeycomb structure consisting of laminated layers of a number of moisture-absorbing sheets, and providing a nose contact piece extending upward from a circular recessed surface on the outer surface of the surface sheet of the honeycomb structure.

CONSTITUTION: When the circular recessed surface 4 of a honeycomb structure is put on the face in opposition to the nostril, and the ear-hung thread 7 of an installation band is hung on the ear to install a moisture holding mask, the nose of a wearing person is laid in the state covered with a nose contact piece 3. At that time, a shaping plate 8 is deformed with the finger to shape the nose contact piece 3 consisting of unwoven fabric and synthetic resin sponge in such a manner that it is adhered to the outer surface of the nose as much ae possible. The exhalation of the wearing person is run into a number of cells opened to the circular recessed surface 4 of the honeycomb structure, and released to the atmosphere from their lower end openings. Hence, the purpose of moisture holding can be effectively attained.
