摘要：
A tungsten oxide powder slurry in which a tungsten oxide powder and an aqueous solvent are mixed, has a feature where D 50 is 20 nm to 10000 nm and D 90 is 100000 nm or less in a particle size cumulative graph of the tungsten oxide powder in the slurry, and where a half-value width of a most intense peak detected at 29° ± 1° in X-ray diffraction analysis (2θ) is 2° or less.
