The present invention aims to provide a masterbatch for foam molding which can be suitably used in molding involving high shear force or molding requiring low molding temperature and which can provide a foam molded article having a high expansion ratio and good appearance quality. The present invention also aims to provide a foam molded article formed from the masterbatch for foam molding. Provided is a masterbatch for foam molding, containing: a base resin; and a thermally expandable microcapsule, the masterbatch having a true specific gravity of 0.80 g/cm 3 or more, the base resin containing an olefin elastomer, the masterbatch containing the thermally expandable microcapsule in an amount of 40 to 300 parts by weight relative to 100 parts by weight of the base resin. |
