The invention discloses a conductive film capable of automatically controlling temperature and uniformly heating. Comprising a conductive thin film, first electrode layers arranged on the edges of the two sides of the surface of the conductive thin film, PTC printing ink arranged on the first electrode layer on at least one side, a second electrode layer arranged on the PTC printing ink, first insulation glue arranged on the side edges of the first electrode layers and used for separating the PTC printing ink from the conductive thin film, and second insulation glue arranged on the conductive thin film. The surface of the conductive film penetrates through the two sides of the conductive film and is provided with a plurality of etching separation lines located between the first electrode layers on the two sides, and the plurality of etching separation lines divide the surface of the conductive film into a plurality of equivalent resistance areas. According to the invention, the conductive film has rapid and u
