Abstract
A spherical inorganic powder having, in a particle size frequency distribution, a first peak having a local maximum value in a particle size region from 0.1 μm or larger to 0.6 μm or smaller, and a second peak having a local maximum value in a particle size region from 1.5 μm or larger to 5.0 μm or smaller, wherein a value of a ratio of a frequency at the local maximum value of the second peak to a frequency at the local maximum value of the first peak is 1.5 or higher and lower than 10.0.
