Provided is a conductive film, which is suitably used in a heating element of a transparent property (a transparent heating element) excellent in visibility and a heating power. The conductive portion of a first conductive film includes mesh patterns having multiple intersecting points (intersecting portions), which are constituted of a plurality of first metal filaments and a plurality of second metal filaments, and the conductive portion between the intersecting portions is formed into an undulating shape having at least one curve. The first conductive film is shaped such that the curves are arcuate and two arcs are formed continuously between the intersecting portions, wherein the protrusion-recess directions of the arcs are opposite to each other. Each arc has a center angle of about 90 degrees. Moreover, the conductive portion has a crossing angle of about 90 degrees. |

1. A conductive film, comprising:
first thin metal wires (12a) extending in a first direction; second thin metal wires (12b) extending in a second direction such that the second thin metal wires cross the first thin metal wires; and a plurality of opening portions formed by the first and second thin metal wires, wherein a combination of the first and second thin metal wires and the opening portions has mesh shapes, wherein the first thin metal wires cross one of the second thin metal wires at a first intersection (24) and, at a second intersection (24), cross another one of the second thin metal wires that is adjacent to said one of the second thin metal wires, wherein the first thin metal wires include two or more first arcs disposed between the first intersection and the second intersection, said first thin metal wires having a wavy line shape formed of the two or more first arcs extending in alternate directions, wherein the second thin metal wires cross one of the first thin metal wires at a third intersection (24) and, at a fourth intersection (24), cross another one of the first thin metal wires that is adjacent to said one of the first thin metal wires, and wherein the second thin metal wires include two or more of second arcs (26) disposed between the third intersection and the fourth intersection, said second thin metal wires having a wavy line shape formed of the two or more second arcs extending in alternate directions. |
