Film, which has a fine structure and is adhered to various materials in an easy and strong manner without an adhesive agent, and a composite structure, film laminate, producing method and etching method, are provided. Solution in which a hydrophobic high molecular compound and a catechol group-containing compound are dissolved in solvent is cast, to form cast film (24). Dew is condensed on an uncovered surface of the cast film (24). The solvent and water droplets upon the condensation are evaporated from the cast film (24), to produce porous film (11). The porous film (11) has a honeycomb structure in which plural pores (12) are formed in one film surface. The pores (12) are in a substantially equal shape and size, and are arranged regularly at a constant pitch. The film surface on a side having the pores (12) of the porous film (11) is a functional surface (13) having an adhesive property. |
