An object of the present invention is to provide a composite oxide particle material formed of zinc molybdate having a high purity and a high circularity. The composite oxide particle material is formed of a composite oxide, of molybdenum and zinc, having an average particle diameter of 0.1 μm or more and 5.0 μm or less, a BET specific surface area of 1 m/g or more and 20 m/g or less, (peak intensity at 26.6° according to XRD)/(peak intensity at 24.2°) of 1.20 or more, an impurity concentration of 1 mass % or less, and a circularity of 0.90 or more. XRD is measured with CuKα radiation.

Composite oxide particle material, method for producing same, filler, filler-containing slurry composition, and filler-containing resin composition

A composite material includes a resinous particulate material, and an inorganic particulate material having a particle diameter being smaller than that of the resinous particulate material, fused welded onto a surface of the resinous particulate material, formed of an inorganic oxide, and including OH groups generated by fuse welding in the surface. The composite particulate material exhibits a degree of sphericity of 0.8 or more, and a has volumetric average particle diameter of from 0.1 to 100 &#x3bc;m.
