To provide a composite oxide particle material composed of zinc molybdate with high purity and high circularity.SOLUTION: A composite oxide particle material is composed of a complex oxide of molybdenum and zinc with an average particle size of 0.1 μm or more and 5.0 μm or less, a BET specific surface area of 1 m2/g or more and 20 m2/g or less, (XRD 26.6° peak intensity)/(XRD 24.2° peak intensity) 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 rays.SELECTED DRAWING: Figure 1 【課題】純度が高く且つ円形度が高いモリブデン酸亜鉛からなる複合酸化物粒子材料を提供することを解決すべき課題とする。【解決手段】平均粒径が０．１μｍ以上、５．０μｍ以下で、ＢＥＴ比表面積が１ｍ２／ｇ以上、２０ｍ２／ｇ以下であり、（ＸＲＤの２６．６°のピーク強度）／（２４．２°のピーク強度）が１．２０以上、不純物濃度が１質量％以下、円形度が０．９０以上であるモリブデンと亜鉛の複合酸化物からなる。ＸＲＤは、ＣｕＫα線により測定する。【選択図】図１
