PROBLEM TO BE SOLVED: To provide a plastisol applicable to an industrial use, wherein the plastisol is prepared by dispersing acrylic polymer fine particles, which contain no vinyl chloride polymer and have good storage stability and good retention of a plasticizer, in a plasticizer. SOLUTION: The acrylic polymer fine particles comprise primary particles P having a core shell structure consisting of a core polymer C and a shell polymer S, wherein the primary particles P have an average particle diameter of 250 nm or larger; the core polymer C and the shell polymer S are copolymers of (meta)acrylic monomer mixtures Mc and Ms respectively; and the weight proportion of Mc to Ms is 10/90-90/10.
