PROBLEM TO BE SOLVED: To provide a method of producing a carbon material film with reduced volume of binder. SOLUTION: In the production method of the carbon material film, in which a carbon material is deposited on the surface of a conductive substrate through electrophoretic migration electrodeposition, a conductive substrate as a negative electrode and an opposite electrode as a positive electrode are dipped in a liquid, in which at least iodine is dissolved in non-protic solvent and a carbon material is dispersed, and direct current electric field is applied between them, or conductive substrate as a positive electrode and a counter electrode as a negative electrode are dipped in a liquid, in which a carbon material is dispersed in the non-protic solvent, and direct current electric field is applied, to deposit a carbon material film on the surface of the conductive substrate. |
