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 (12) of a first conductive film (10A) includes mesh patterns (22) having a multiple intersecting points (intersecting portions (24)), which are constituted of a plurality of first metal filaments (12a) and a plurality of second metal filaments (12b), and the conductive portion (12) between the intersecting portions (24) is formed into an undulating shape having at least one curve. The first conductive film (10A) is shaped such that the curves are arcuate and two arcs (26) are formed continuously between the intersecting portions (24), wherein the protrusion-recess directions of the arcs (26) are opposite to each other. Each arc (26) has a center angle of about 90 degrees. Moreover, the conductive portion (12) has a crossing angle of about 90 degrees. |
