A graphene sheet film as a film-like assembly of two or more graphene sheets 11 to 25 is provided. The graphene sheet film uses a graphene sheet assembly 101 that includes: first carbon nanotubes 31 to 48 that join the graphene sheets 11 to 25 to each other and form graphene sheet laminates 61 to 65 in which the graphene sheets 11 to 25 are laminated with the sheet planes being paralleled to each other; and second carbon nanotubes 51 to 56 that connect the graphene sheet laminates 61 to 65 to each other. This makes it possible to provide a graphene sheet film having high capacitor performance with respect to energy density and output density, a method for producing the same, and a graphene sheet capacitor using such graphene sheet films.

A graphene sheet assembly film comprising plural graphene sheet laminates each of which comprises two or more graphene sheets laminated parallel to each other via first carbon nanotubes, the plural graphene sheet laminates being electrically and mechanically, three-dimensionally connected to each other via second carbon nanotubes.
A method for producing a graphene sheet assembly film, the method comprising the steps of adding carbon nanotubes to an aqueous solution of chemically reduced graphene sheets uniformly dispersed therein and producing a mixed solution of the graphene sheets and the carbon nanotubes, and filtering the mixed solution.
