<P>PROBLEM TO BE SOLVED: To provide a three-dimensional mask having superior humidification effects while preventing the deterioration of comfort when being worn and to provide a simple usage method of the three-dimensional mask. <P>SOLUTION: The three-dimensional mask is formed with a mask body for covering the nose and mouth of a wearer with a sheet-like member having air permeability and configured to retain a forward-swelled three-dimensional shape when being worn. The mask body has a water-absorbing sheet formed by using water-absorbing polymer, interposed in its width-directional intermediate portion, and a section from the outer surface to the water-absorbing sheet has higher water permeability than a section from the inner surface to the water-absorbing sheet. <P>COPYRIGHT: (C)2010,JPO&INPIT |
