摘要：
A visible-light-responsive photocatalyst powder includes a tungsten oxide powder. The tungsten oxide powder has color whose a* is −5 or less, b* is −5 or more, and L* is 50 or more when the color of the powder is expressed by an L*a*b* color system. Further, the tungsten oxide powder has a BET specific surface area in a range of 11 to 820 m2/g.
