Provided is a method for manufacturing a foam-molded article by molding
between molds a parison with a foam layer formed by extruding an
expandable molten resin composition, obtained by melt-kneading a
polyethylene resin and a physical foaming agent, to an area of low
pressure from a die, wherein the polyethylene resin is selected from
those having a melt flow rate of 0.1 to 25 g/10 minutes and a melt
tension of not less than 1.5 cN, and wherein the apparent density of the
foam layer in the foam-molded article is about 0.04 to 0.3 g/cm.sup.3.
