The present invention relates to a polyvinyl chloride composition for powder molding, including: a polyvinyl chloride (A) having an average particle diameter of 50 to 500 µm; a polyvinyl chloride (B) having an average particle diameter of 0.01 µm or more and less than 50 µm; a plasticizer; and an alkyl phosphate. The average polymerization degree of the polyvinyl chloride (A) is 1350 or more. The alkyl phosphate contains a mono-alkyl phosphate, and the number of carbon atoms of an alkyl group in the alkyl phosphate is 5 or more. The blending amount of the polyvinyl chloride (B) is 5 to 40 parts by mass, the blending amount of the plasticizer is 110 to 150 parts by mass, and the blending amount of the alkyl phosphate is 0.1 to 3.0 parts by mass with respect to 100 parts by mass of the polyvinyl chloride (A). Thereby, the present invention provides a polyvinyl chloride composition for powder molding from which a molded body having favorable heat aging resistance, high adhesiveness to a polyurethane foam layer, and easy releasability from a mold for slush molding, with less odor, can be produced, and a polyvinyl chloride molded body and a laminate.
