This copper-and-titanium-containing composition is a copper-and-titanium-containing composition that contains: a titanium oxide including a crystalline rutile-type titanium oxide and a divalent copper compound. The crystalline rutile-type titanium oxide is a titanium oxide having a half-value total width of no more than 0.65 for the strongest diffraction peak corresponding to the rutile-type titanium oxide, in an X-ray diffraction pattern plotting the diffraction line intensity relative to the diffraction angle (2theta) using a Cu-Kalpha ray, and, as a result, has excellent anti-viral properties in bright and dark locations, and excellent organic compound degradability in bright locations.本發明之含有銅及鈦之組成物,其係含有包含結晶性金紅石型氧化鈦之氧化鈦與2價銅化合物之含有銅及鈦之組成物,其特徵為前述結晶性金紅石型氧化鈦係為在將繞射線強度對於Cu-Kα線所致之繞射角度2θ予以作圖之X光繞射圖型中,因為對應金紅石型氧化鈦之最強繞射波峰之半值全寬為0.65度以下之氧化鈦,在明處及暗處抗病毒性優異、在明處有機化合物分解性優異。
