Zusammenfassung:An object is to provide expandable thermoplastic resin particles that can achieve both high heat insulating property and high expandability and that contain graphite having a mean particle size of less than 2.5 µm. The expandable thermoplastic resin particles contain graphite in a specific amount, a thermoplastic resin, and a blowing agent, the graphite has a mean particle size falling within a specific range, and span "S" (S = (D90-D10)/D50), which indicates the spread of particle size distribution of graphite, is not more than 4.0.
