Abstract: An object of the present invention is to provide a novel method for forming a carbonaceous structure comprising minute carbon bodies such as CNTs. A method for forming a carbonaceous structure on the surface of a substrate, comprising a step of forming a layered structure by at least partially filling a gap between a porous membrane which can hold a dispersion medium and a substrate with a minute-carbon-body dispersion liquid comprising the minute carbon bodies and the dispersion medium, and a step of removing the dispersion medium by at least partially taking the dispersion medium out of the layered structure through the porous membrane and/or the substrate.

Abstract: According to an embodiment of the present invention, a conductive membrane transfer sheet including a first release sheet and a conductive membrane is provided. The first release sheet includes a liquid-permeable sheet. The conductive membrane includes a conductive fiber supported on a first major surface of the first release sheet. The first release sheet and the conductive membrane contain a first liquid.
