PROBLEM TO BE SOLVED: To provide an expansion molded product of styrenic resin particles for cutting, which produces little thickness variation at slicing and yields a foamed film showing good surface quality in high yield. SOLUTION: The expansion molded product of styrenic resin particles for cutting is obtained from the expandable styrenic resin particles, includes 5-50 wt.% acrylonitrile, has a density of 100-500 kg/m<SP>3</SP>and has no particle-shaped, non-expanded parts inside the expansion molded product of styrenic resin particles.
