PROBLEM TO BE SOLVED: To obtain a molding having uniform and fine foamed cells by dispersing a powdery inorganic blowing agent into a similarly powdery carrier resin without melting and kneading the resin in order to uniformly disperse a blowing agent into a thermoplastic resin. SOLUTION: An inorganic blowing agent such as a carbonate having 0.001-0.1mm average particle diameter in an amount of 0.1-50 pts.wt. is mixed with and dispersed into 100 pts.wt. of a thermoplastic resin having 0.01-1.0mm average particle diameter without melting the thermoplastic resin and is used for molding.
