摘要： A method of manufacturing an article containing silicon carbide as a main component includes a step of laying raw material powder, and a step of irradiating the raw material powder with a laser beam, wherein the raw material powder contains 95 mol % or more of silicon carbide, and wherein, in the step of irradiating the raw material powder with the laser beam, the raw material powder is irradiated with the laser beam to decompose the silicon carbide in at least a part of an irradiation portion of the laser beam into silicon and carbon and to turn the silicon or the carbon into melt.
