Zusammenfassung:The silicon carbide powder is a powder of silicon carbide having an α-type crystal system, where the number of small corner portions among corner portions on a surface of a primary particle of silicon carbide constituting the powder of silicon carbide is 2.5 or less per one primary particle. The small corner portion is a corner portion, among corner portions present in a contour of the primary particle in a projection image of the primary particle, where twice a curvature radius of the corner portion is 1/5 or less of a Heywood diameter of the projection image of the primary particle.
