Abstract
A filter molded article using a graphene with water passage holes having a desired size is produced in a simple step. A method for producing a filter molded article having a graphene layer as a filtering material is characterized by including a step of forming a supportlayer on a surface of a graphenelayer formed on initial substrates for a grapheneand, a step of forming water passage holes in the supportlayer, a step of removing the initial substrates for a grapheneand, and a step of forming water passage holes by heating and holding the graphenelayer at a low temperature in the air containing oxygen of 160 to 250° C. for a predetermined time.
