Abstract
A plate-like alumina particle, in which a ratio I(006)/I(ll3) of a peak intensity I(006) at 20=41.6±0.3 degrees which corresponds to a (006) face to a peak intensity I(113) at 20=43.3±0.3 degrees which corresponds to a (113) face of diffraction peaks obtained by X-ray diffraction measurement using a Cu-Ka ray, is 0.2 or more. A method for manufacturing the plate-like alumina particle including mixing an aluminum compound including an aluminum element, a molybdenum compound including a molybdenum element, and a shape-controlling agent to produce a mixture and firing the mixture.
