A porous structure () provided with a pattern that is composed of a conductive polymer, which comprises a porous body () and a pattern () that is composed of a conductive polymer and arranged on the porous body (). The porous body () is preferably a gel, and a dopant may be added to the pattern () that is composed of a conductive polymer. If an agarose gel is used as the gel () and a PEDOT electrode (A) is used as the pattern () that is composed of a conductive polymer in the porous structure () which is provided with the pattern () that is composed of a conductive polymer, the porous structure () can be used as an electrode for cell stimulation. The porous structure () provided with the pattern () that is composed of a conductive polymer can be produced by an electropolymerization method.

The invention provides a method for evaluating a corneal disorder quantitatively and is applicable to living eyes. In particular, the invention provides a method for measuring a corneal transepithelial electric resistance, which method comprises: (1) a step of placing a first electrode on the cornea and a second electrode on the conjunctiva; and (2) a step of flowing an electric current between the first electrode and the second electrode to measure the electric resistance. The invention also provides a device for measuring a corneal transepithelial electric resistance value.
