The foamable resin composition of the present invention is characterized by comprising starch, a synthetic resin, an alkaline compound, and water in an amount of 10 to 40 parts by weight with respect to 100 parts by weight of the starch, wherein the synthetic resin content is 0.02 to 10 wt %. The alkaline compound is preferably at least one selected from the group consisting of an alkali metal hydrogen carbonate, an alkali metal carbonate, an alkali earth metal hydrogen carbonate, and an alkali earth metal carbonate. The foam obtained by using the foamable resin composition of the present invention is free from a practical problem such as cushioning properties and the like, and has a cost advantage as an amount of a synthetic resin is extremely small. |
