PROBLEM TO BE SOLVED: To provide organic clay capable of obtaining sufficient dispersion performance, in a state where the distance between layers in organic clay with a layered crystal structure is sufficiently widened, by easily intercalating therein, and to provide its manufacturing method. SOLUTION: After a dehydration stage where the distance between crystal layers in organic clay is sufficiently widened, namely, before a drying stage, a resin additive, e.g. either one or a combination among a flame retarder, an ultraviolet absorber, a nucleating agent, a heavy metal deactivator, an organic blowing agent and a lubricant dissolved or dispersed into an organic solvent is added and mixed in advance, and is intercalated between the crystal layers, and drying and pulverizing are performed, so that the organic clay in which a new compound is intercalated is obtained.
