METHOD FOR PRODUCING POROUS RESIN SUBSTRATE HAVING HOLE BORED THERETHROUGH AND POROUS RESIN SUBSTRATE PROVIDED WITH HOLE HAVING INNER WALL SURFACE IMPARTED WITH ELECTROCONDUCTIVITY

摘要

A method for producing a porous resin substrate having a hole bored therethrough, which comprises a step (1) of boring at least one hole passing through a porous resin substrate formed form a resin material containing a fluorine-containing polymer in the thickness direction, a step (2) of contacting the surface of the inner wall with an etching solution containing an alkali metal, to subject the surface to an etching treatment, and a step (3) of contacting a modified layer formed by the etching treatment with a compound having oxidizing power or a solution thereof, to thereby remove said modified layer; the method for producing a porous resin substrate which further comprises imparting electroconductivity to the surface of the inner wall of said hole bored therethrough.
