PROBLEM TO BE SOLVED: To provide foamable thermoplastic resin particles that provides reduced amount of falling-away powdery coating agent during the transportation to a prefoaming machine and a foam molding machine, excellent flowability, and a shortened transportation time, and can form molded foams with excellent gloss. SOLUTION: These foamable thermoplastic resin particles have their surfaces coated with a skin layer. The layer comprises, based on 100 pts.wt. of the foamable thermoplastic resin particles, 0.1-0.6 pts.wt. of an aqueous mixture solution obtained by mixing a polyalkylene glycol and a polyvinyl resin in a weight ratio (the polyalkylene glycol/the polyvinyl resin) of 4-50, and having viscosity of 100-300 mPa×s, and 0.03-0.6 pts.wt. of a powdery coating agent.
