The present invention provides a steam generating unit that causes no leakage of fine particle powder, and can be applied to any application object or any site. In this steam generating unit, a steam generating composition that contains metal powder, a salt, and water, and that releases steam in conjunction with the oxidation of the metal powder, is contained in a bag. That bag is configured from moisture-permeable sheet exhibiting a moisture permeability of 1000 g/m<2>/24h or higher but 10000 g/m<2>/24h or lower, as defined by JIS Z0208, and a gas permeability of 200 seconds/100 cm<3> or lower, as defined by JIS P8117. This invention also provides a mask or an eye pillow containing said unit and the use thereof for applying steam to mucous membrane.
