Provided is a conductive film suitable for use in a transparent heating element having superior visibility and heat generation properties. A conductor of a first conductive film has a mesh pattern which has a plurality of lattice cross points (intersections) formed by a plurality of first metal nanowires and a plurality of second metal nanowires. The conductor between intersections is formed in a wave-like shape having at least one curve. The array period of an arc of one first metal nanowire from among parallel adjacent first metal nanowires is one period. The array period of an arc of another first metal nanowire constitutes two periods. Similarly, the array period of an arc of one second metal nanowire is one period. The array period of an arc of another second metal nanowire constitutes two periods.
