Abstract:
A method of producing a functional element, comprising:preparing a substrate for a pattern-formed structure having a characteristic-modifiable layer with at least one characteristic at a surface thereof that can be modified by the action of a photocatalyst; arranging the substrate for the 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 the photocatalyst, such that the characteristic-modifiable layer faces the photocatalyst-containing layer with a gap of no larger than 200 &mgr;m therebetween; irradiating energy to the characteristic-modifiable layer by way of the photocatalyst-containing layer from a predetermined direction, and modifying the at least one characteristic of a surface of the characteristic-modifiable layer, thereby forming a pattern at the characteristic-modifiable layer; and providing a functional portion of the pattern at the characteristic-modifiable layer.
