PROBLEM TO BE SOLVED: To provide an injection-foamed molding which has light weight and high rigidity, is uniform in cell shape and cell density, and has excellent external appearance.SOLUTION: The injection-foamed molding is obtained by adding a foaming agent to a propylene-based resin composition, which contains 60-99 pts. wt. of a propylene-based block copolymer (A) satisfying specific required items (a1)-(a5) simultaneously and 1-40 pts. wt. of an ethylene-based polymer (B) satisfying specific required items (b1)-(b5) simultaneously (on condition that the total of (A) and (B) is 100 pts. wt.), and injection-foaming the foaming agent-added propylene-based resin composition. |
