Abstract: The present invention relates to a method for producing foam and foam produced thereby. The method for producing foam includes a step for producing foam by kneading and injection molding a first extrusion product and a second extrusion product, wherein the first extrusion product is obtained by extruding a first composition including an aromatic vinyl-based resin, and the second extrusion product is obtained by extruding a second composition including a polyamide resin and a foaming agent.
