This method for producing an additively-manufactured article comprises: a step for supplying, on a substrate, a powder material obtained by mixing a stellite alloy-containing first powder and a tungsten carbide-containing second powder; and a step for irradiating the supplied powder material with a weaving laser beam to laminate, on the substrate, at least a build-up layer obtained by melting and solidifying the powder material. The step for laminating the build-up layer is performed such that 20≤A≤35, 2.2≤B≤2.9, and 5 mass%≤R2≤15 mass% are satisfied, where A is a laser heat input index, B is a powder supply rate index, and R2 is the proportion of the second powder contained in the powder material.
