description The purpose is to provide spherical alumina particles having low surface residual Na level and low agglomeration degree, a production method of the same and a resin composite composition comprising the same. Spherical alumina particles have an average diameter of 0.4-1.9 [mu]m, a specific surface area of 1.0-5.0 m2/g, a surface residual Na of 200 ppm or less, a Na2O content of 1,000 ppm or less, an agglomeration degree of 1.0% or less and a degree of circularity of 0.9 or more. A production method of the same and a resin composite composition comprising the same are also provided.
