PROBLEM TO BE SOLVED: To obtain expanded moldings of a resin by blending especially a functional resin having less expanding characteristic and providing a laminar dispersion structure, and preferably to provide an olefinic thermoplastic resin having excellent appearance, a flame retardant characteristic and secondary processability. SOLUTION: The expanded moldings comprise at least resin (A) and a resin (B) in which either of (A) and (B) contains non-polyolefin resin, and the resin (A) forms an expanded moldings while the resin (B) forms laminar dispersion structure in the cell membrane of the expanded moldings.
