Abstract of the Disclosure A pre-expanded particle of a polyolefin resin, characterized in that a resin in which 0.1 to 10 parts by weight of a polymer containing carboxyl group is contained in 100 parts by weight of a polyolefin resin is used as a base material-resin, and the cell diameter is from 200 to 500 µm. The article molded in a mold from the pre-expanded particles is small in the shrinkage and the strain and is excellent in the appearance, and the productivity of the foams is raised.
