PROBLEM TO BE SOLVED: To provide a pattern forming body using a photocatalyst. SOLUTION: The photocatalyst-containing layer has a photocatalyst-containing layer on a substrate, and the photocatalyst-containing layer is a layer containing a substance whose wettability is changed by the action of the photocatalyst upon exposure of the pattern. A layer containing a substance whose wettability changes by an action, or a layer having a photocatalyst-containing layer on a substrate and a layer which is decomposed and removed by the action of a photocatalyst by exposure of a pattern on the photocatalyst-containing layer, or A pattern forming body having a composition layer comprising a photocatalyst, a substance decomposed by the action of a photocatalyst upon exposure of a pattern, and a binder, and recording a pattern by changing wettability upon exposure.
