Abstract

The purpose is to produce a molded filter body using graphene having water passage holes with a desired size by an easy process. A method for producing a molded filter body having a layer of grapheneas a filter medium, includes the steps of: forming a layer of a supporton a surface of graphite; forming support water passage holes in the layer of the support; peeling the layer of the supportfrom the graphitein a state of attaching the layer of grapheneon the surface of the graphiteto the layer of the support; and holding the layer of grapheneby heating at a low temperature for a predetermined time in the air containing oxygen at 160 to 250° C. and forming graphene water passage holes.
