The invention claimed is: 1. A method for imparting adsorbability of moisture- or a protein to a material by adding a moisture- or protein-adsorbability imparting agent to a material selected from the group consisting of food wrapping materials, filtration aid agents, sanitary articles, covering materials for wounds, insulation substrates, coating materials for semiconductor devices, cosmetics, and compositions containing synthetic fibers, whereinthe moisture- or protein-adsorbability imparting agent comprises a porous silica having a hexagonal pore structure, an average pore size of from 0.8 to 5 nm, an average particle size of 50 nm to 100 μm, a specific surface area of from 400 to 2000 m2/g, and a pore volume of from 0.1 to 3.0 cm3/g and the moisture- or protein-absorbability imparting agent further comprises a polyglycerol fatty acid ester obtained by esterification of a polyglycerol having an average degree of polymerization of 3 or more, and a fatty acid.
