The present invention relates to a polyvinyl chloride composition for powder molding, including: a polyvinyl chloride (A) having an average particle diameter of 50 µm or more and 500 µm or less and an average polymerization degree of 1350 or more; a polyvinyl chloride (B) having an average particle diameter of 0.01 µm or more and less than 50 µm; a plasticizer; and a phosphate. The phosphate is a polyoxyalkylene alkyl phosphate. The blending amount of the polyvinyl chloride (B) is 5 parts by mass or more and 40 parts by mass or less, the blending amount of the plasticizer is 120 parts by mass or more and 150 parts by mass or less, and the blending amount of the polyoxyalkylene alkyl phosphate is 0.1 parts by mass or more and 3.0 parts by mass or less 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.
