The present invention relates to a filler particle, which is characterized in that it is composed of a composite zinc oxide represented by the following chemical formula (1); and relates to a resin composition, a grease, and a coating composition containing the filler particle. Furthermore, according to the present invention, filler particles having stable insulating properties, and resin compositions, greases, and coating compositions having the filler particles can be obtained. Wherein, M in the following chemical formula (1) is Mg or Co, and if the valence of M is n, then x+ny/2=1. Zn x M y O (1). |
