Abstract
A photocatalytic filter includes a filter substrate, the filter substrate being a porous metal, and a photocatalyst fixed to the filter substrate. When a thickness of the porous metal is t (mm) and an average cell number per inch of the porous metal is C (ppi), a product (t×C) of the thickness t and the average cell number C is from 100 or more to 400 or less.
