Patent ID: 7846647

Claim:
A method of producing a pattern-formed structure, comprising the processes of: preparing a substrate for a pattern-formed structure having a characteristic-modifiable layer whose characteristic at a surface thereof can be modified by the action of photocatalyst; arranging the substrate for a pattern-formed structure and a photocatalyst-containing layer side substrate having a photocatalyst-containing layer formed on a base material, the photocatalyst-containing layer containing photocatalyst, such that the characteristic-modifiable layer faces the photocatalyst-containing layer with a gap of no larger than 200 μm therebetween; and irradiating energy to the characteristic-modifiable layer from a predetermined direction, and modifying a characteristic of a surface of the characteristic-modifiable layer, thereby forming a pattern at the characteristic modifiable layer, wherein the photocatalyst-containing layer side substrate comprises the base material, the photocatalyst-containing layer formed on the base material, and a light-shielding portion formed, in a pattern-like configuration, on the photocatalyst-containing-layer side substrate, and the irradiation of energy at the pattern forming process is carried out from a side of the substrate for a pattern-formed structure.
