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 graphene 2 as a filter medium, includes the steps of: forming a layer of a support 5 on a surface of graphite 1; forming support water passage holes in the layer of the support 5; peeling the layer of the support 5 from the graphite 1 in a state of attaching the layer of graphene 2 on the surface of the graphite 1 to the layer of the support 5; and holding the layer of graphene 2 by 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.
