Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a titanium oxide catalyst containing a catalyst metal, capable of showing a catalytic action even under a high temperature condition.SOLUTION: A titanium oxide catalyst 1 includes a titanium oxide nanoparticle aggregate 10 formed by aggregating titanium oxide nanoparticles 11 which are nanoparticles of titanium oxide, and ruthenium particles 20 having a smaller particle size than the particle size of the titanium oxide nanoparticle aggregate 10 and the titanium oxide nanoparticles 11, and supported dispersedly on the surface of the titanium oxide nanoparticle aggregate 10.SELECTED DRAWING: Figure 1 【課題】本発明は、高温条件下でも触媒作用を発揮することができる、触媒金属を含有した酸化チタン触媒を提供することを目的とする。【解決手段】酸化チタンのナノ粒子である酸化チタンナノ粒子１１が凝集した酸化チタンナノ粒子凝集体１０と、酸化チタンナノ粒子凝集体１０および酸化チタンナノ粒子１１の粒子径よりも小さな粒子径を有するとともに、酸化チタンナノ粒子凝集体１０の表面に分散して担持するルテニウム粒子２０とを含有する酸化チタン触媒１であることを特徴とする。【選択図】図１
