A method for producing a skin-covered foamed molded article, comprising the steps of: extruding a melt of a polypropylene-based resin composition to form a parison in a softened state; blow-molding the parison into a skin 1 in which a hollow interior space is formed; inserting heating medium supply pins 2 through the skin 1; filling thermoplastic resin expanded beads in the hollow interior space of the skin 1; and supplying a heating medium into the hollow interior space of the skin 1 through the heating medium supply pins 2 to fuse-bond the expanded beads filled in the hollow interior space of the skin 1 to each other, characterized in that the polypropylene-based resin composition contains at least one crystallization promoter selected from aromatic phosphoric ester metal salt compounds and sorbitol compounds, and satisfies the following requirements and: the polypropylene-based resin composition has a tensile elongation at break at 80°C of 300 to 1,000% according to JIS K 7127; and the polypropylene-based resin composition has a half-crystallization time at 130°C of 5 to 50 seconds, wherein the half-crystallization time is determined by a method in which the polypropylene-based resin composition is formed into a film-like sample, the film-like sample is mounted on a support and is placed in an oil bath maintained at 130°C, a measurement value of transmitted light of the film-like sample is measured by the crystallization speed analyzer, and the half-crystallization time is calculated from the measurement value and an Avrami equation. extruding a melt of a polypropylene-based resin composition to form a parison in a softened state; blow-molding the parison into a skin 1 in which a hollow interior space is formed; inserting heating medium supply pins 2 through the skin 1; filling thermoplastic resin expanded beads in the hollow interior space of the skin 1; and supplying a heating medium into the hollow interior space of the skin 1 through the heating medium supply pins 2 to fuse-bond the expanded beads filled in the hollow interior space of the skin 1 to each other, characterized in that the polypropylene-based resin composition contains at least one crystallization promoter selected from aromatic phosphoric ester metal salt compounds and sorbitol compounds, and satisfies the following requirements and: the polypropylene-based resin composition has a tensile elongation at break at 80°C of 300 to 1,000% according to JIS K 7127; and the polypropylene-based resin composition has a half-crystallization time at 130°C of 5 to 50 seconds, wherein the half-crystallization time is determined by a method in which the polypropylene-based resin composition is formed into a film-like sample, the film-like sample is mounted on a support and is placed in an oil bath maintained at 130°C, a measurement value of transmitted light of the film-like sample is measured by the crystallization speed analyzer, and the half-crystallization time is calculated from the measurement value and an Avrami equation. the polypropylene-based resin composition has a tensile elongation at break at 80°C of 300 to 1,000% according to JIS K 7127; and the polypropylene-based resin composition has a half-crystallization time at 130°C of 5 to 50 seconds, wherein the half-crystallization time is determined by a method in which the polypropylene-based resin composition is formed into a film-like sample, the film-like sample is mounted on a support and is placed in an oil bath maintained at 130°C, a measurement value of transmitted light of the film-like sample is measured by the crystallization speed analyzer, and the half-crystallization time is calculated from the measurement value and an Avrami equation.
