    摘要： Provided is a porous electrode substrate having high mechanical strength, good handling properties, high thickness precision, little undulation, and adequate gas permeability and conductivity. Also provided is a method for producing a porous electrode substrate at low costs. A porous electrode substrate is produced by joining short carbon fibers (A) via mesh-like of carbon fibers (B) having an average diameter of 4 μm or smaller. Further provided are a membrane-electrode assembly and a polymer electrolyte fuel cell that use this porous electrode membrane. A porous electrode substrate is obtained by subjecting a precursor sheet, in which short carbon fibers (A) and short carbon fiber precursors (b) having an average diameter of 5 μm or smaller have been dispersed, to carbonization treatment after optional hot press forming and optional oxidization treatment.

    摘要： A skin-covering sheet for impregnation with a cosmetic preparation according to the present invention includes a non-woven fabric in which a splittable conjugate fiber containing at least two components as viewed in fiber cross-section, namely a polyethylene component and another polymer component, and a hydrophilic fiber are blended, and hydroentangled. The conjugate fiber is partially split and includes a polyethylene ultrafine fiber having a fineness of 0.6 dtex or less. A face mask according to the present invention includes the skin-covering sheet for impregnation with a cosmetic preparation impregnated with 500 to 2000 mass % of a liquid containing a cosmetic preparation. It is therefore possible to obtain a skin-covering sheet for impregnation with a cosmetic preparation and a face mask that have good impregnating ability of a cosmetic liquid into the sheet layer, cause very little irritation to the skin, and are soft in texture.
