A method for producing a foamed body includes: forming a foamed layer precursor including applying a coating liquid onto a base to form a liquid film and applying an ink onto the liquid film by an inkjet method, where the coating liquid contains a foaming agent and an active energy ray curable material having a radical-polymerizable functional group, the active energy ray curable material contains a multifunctional active energy ray curable material having two or more radical-polymerizable functional groups, and the ink contains a foaming accelerator having a radical-polymerizable functional group; and foaming a desired position of the foamed layer precursor by heating to form a foamed layer. A functional group equivalent of the radical-polymerizable functional group in the foaming accelerator is greater than a functional group equivalent of the radical-polymerizable functional group in the active energy ray curable material.
