Abstract:
A polytetrafluoroethylene porous body which is produced by molding a polytetrafluoroethylene mixture, including a polytetrafluoroethylene powder and a pore-forming agent, into a predetermined shape, and subsequently removing the pore-forming agent. The pore-forming agent includes (a) one or more powders selected from a group consisting of dicarboxylic acid powders and benzoic acid powders, and (b) an organic solvent.
