PROBLEM TO BE SOLVED: To obtain both a highly packed foamable resin composition excellent in properties, having highly hydrogen chloride scavenging ability when being burnt, comprising a vinyl chloride-based resin in a highly packed state of calcium carbonate, which is foamable and moldable, and to provide its molding. SOLUTION: This composition is obtained by blending 100 pts.wt. of a vinyl chloride-based resin with 50-300 pts.wt. of a heavy calcium carbonate or precipitated calcium carbonate having <=1μm particle diameter as an inorganic fine particle filler, 0.05-20 pts.wt. of a blowing agent and 3-50 pts.wt. of a polymer processing auxiliary excellent in compatibility.
