▎ 摘　　要

NOVELTY - A transparent conductive film (10) comprises a transparent base material (12), graphene (14) provided on the transparent base material, and a polymethylmethacrylate layer (16) provided on the graphene. The thickness of the polymethylmethacrylate layer is 20-150 nm. USE - Transparent conductive film is used in touchscreen and flexible heater (all claimed). ADVANTAGE - The transparent conductive film has low resistance without deterioration of graphene. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) touchscreen, which comprises the transparent conductive film, and a protective film which protects polymethylmethacrylate layer of the transparent conductive film; and (2) flexible heater, which comprises the transparent conductive film, a pair of contact electrodes in contact with the graphene, and a power source connected to the pair of contact electrodes. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the transparent conductive film.
