Materials not releasing gaseous organic materials during use are used as a dry-type sealing material such as a gasket disposed upon mounting an air filter to an opening of a ceiling or the like, a wet-type sealing material filled and used in a gap for connecting wall materials or partitionings, a vinyl chloride sheet or a vinyl chloride cloth as a facing material for walls and floors. Specifically, a carboxylic acid ester having a molecular weight of not less than 400 is used as a plasticizer, a phenolic compound having a molecular weight of not less 300 is used as an antioxidant, an aliphatic hydrocarbon having not less than 19 carbon atoms (for example, microcrystalline wax) is used as a lubricant, and an alkylamine ethylene oxide adduct having a molecular weight of not less than 350 is used as an antistatic agent.

[ What is claimed is:] [1.] A clean room for manufacturing semiconductors, having a building component comprising a polyvinyl chloride resin and an additive which, when measured by Purge & Trap-Gas Chromatography/Mass Spectroscopy, does not release gaseous organic materials in amounts that are adsorbed on silicon wafers being processed in the clean room, as any one of a floor facing material for covering the surface of a floor, a wall facing material for covering the surface of a wall, a skirt for covering a vicinity of a boundary between the wall and the floor, a crown for covering a boundary between a ceiling and the wall, and a partition sheet.
