Abstract
A heating film includes a base layer and a heating layer. The heating layer is disposed on a surface of the base layer and is defined with multiple equivalent heating zones. Each equivalent heating zone is disposed with a heating wire. The outside of the equivalent heating zones is disposed with an input conductive wire and an output conductive wire. The input conductive wire and the output conductive wire are connected to each heating wire in parallel. Each of the equivalent heating zones has substantially the same area. The heating wire in each equivalent heating zone has substantially the same path width and total path length.
