Expandable resin particles that have a reduced VOC content, a method of producing the expandable resin particles, and a foamed molded product that has reduced VOC emission are provided. The expandable resin particles contain a base material resin containing, as a structural unit, a styrene unit and an acrylonitrile unit and an expanding agent. The expandable resin particles have a styrene content and an ethylbenzene content each of which is not more than a specific amount.

Foamable resin particles and method of producing same, and foamed molded body

An expandable thermoplastic resin particle including a polymer obtained by a process including polymerizing monomers including 60 to 80 parts by weight of &#x3b1;-methylstyrene and 40 to 20 parts by weight of acrylonitrile. A content of residual monomeric components in the expandable thermoplastic resin particle is not more than 0.5% by weight. When an expanded mold article is produced from the expandable thermoplastic resin particle at an expansion ratio of 10 times, foam cells in a cross section of the expanded mold article have an average chord length of from 20 &#x3bc;m to 60 &#x3bc;m.
