The disclosure relates to a metal nanowire film. The metal nanowire film includes a substrate and a number of first metal nanowire bundles located on the substrate. The number of first metal nanowire bundles are parallel with and spaced from each other. Each of the number of first metal nanowire bundles includes a number of first metal nanowires parallel with each other. The first distance between adjacent two of the number of first metal nanowires is less than the second distance between adjacent two of the number of first metal nanowire bundles.
