Abstract: A particulate material is mainly composed of alumina, has a volume average particle diameter of from 70 to 200 μm, has a degree of sphericity of from 0.89 or more to less than 0.99, has a degree of alfa-aluminization of from 40 to 85%, and produces a result of 0.017 g or less in an abrasion test for equipment.

Abstract: A silicone-coated filler comprises: a particulate material mainly composed of an inorganic oxide formed by oxidizing a predetermined element; a first silicone structure bonded to a surface of the particulate material by way of a “-‘the predetermined element’-OSi—” structure; and a second silicone structure including a cross-linking structure with a carbon-carbon structure directly bonded to a silicon atom of the first silicone structure, and a polysiloxane structure bonded to the cross-linking structure.
