Abstract
Inorganic powder includes spherical alumina powder and spherical silica powder, in which when the inorganic powder is measured using a wet flow type image analyzer, a sphericity of a particle size of 5-10 μm is represented by S1, a sphericity of a particle size of 10-20 μm is represented by S2, a sphericity of a particle size of 20-30 μm is represented by S3, a sphericity of a particle size of 30-45 μm is represented by S4, and a sphericity of a particle size of more than or equal to 45 μm is represented by S5, at least two of S1, S3, S4, and Ss are more than or equal to 0.89, and S2 is more than or equal to 0.75 and less than 0.89.
