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 support 3 layer on a surface of a graphene 1 layer formed on initial substrates for a graphene 2 and 9, a step of forming water passage holes in the support 3 layer, a step of removing the initial substrates for a graphene 2 and 9, and a step of forming water passage holes by heating and holding the graphene 1 layer at a low temperature in the air containing oxygen of 160 to 250° C. for a predetermined time.
