NOVELTY - The embodiment of the invention claims a writing pen, belonging to the technical field of conductive pen. The writing pen includes: pen core, the pen core comprises a core rod and a pen point, the first end of the core rod is connected with the pen point; the core rod is provided with an ink cabin for storing graphene conductive ink, which is located at the first end of the core rod; the first end of the pen point is connected with the ink chamber; the second end of the pen point is used for outputting graphene conductive ink, the graphene conductive ink forms handwriting; and a pen cap, the pen cap comprises a wiping sheet with organic solvent and a fixing piece, the wiping sheet is detachably set on the fixing piece. The graphene conductive ink in the invention can be quickly dried at room temperature, pure aqueous, non-toxic and harmless, excellent conductivity, good adhesive force, good writing adaptability, long effective conductive pen track, stable circuit. The writing pen can be on the paper board, plastic film, wall, fabric and other any object surface (except skin), drawing pattern, fast drying and curing to form a conductive circuit.
