Abstract

The invention provides a structured material characterized in having, on a substrate (11), a layer (12) having tubular (13) pores positioned uniaxially parallel to the interface of the substrate and the layer and supporting a conductive polymer material (14,21) having a function of a surfactant (22) therein. The invention also provides a method for producing the above structure material characterized by the steps of providing a substrate having the anisotropy on a surface, applying a solution containing a surfactant having a functional group for polymerization in the molecular structure, a solvent therefor, and a solute different from the surfactant to the substrate, and a step of standing for a predetermined time for causing the surfactant to assemble in a predetermined direction based on the anisotropy of the substrate.
