The invention discloses a composite conductive film which is characterized in that the composite conductive film comprises a first composite layer and a gum layer which are stacked in sequence; wherein the first composite layer comprises a conductive layer and a base film; the conductive layer and the base film form a conductive film; the base film is a flexible base film; the back adhesive layer is arranged on one side, opposite to the conductive layer, of the base film, and the adhesive force between the back adhesive layer and the base film is greater than or equal to 400g/25mm; the back adhesive layer is used for being attached to a device to be glued. The composite conductive film disclosed by the invention is provided with the back adhesive layer, can be directly laminated through the back adhesive layer when a scene needs to be laminated, is convenient to repair, and saves the repair cost. 本发明公开一种复合导电膜，其特征在于，所述复合导电膜包括依次层叠的：第一复合层和背胶层；其中，所述第一复合层，包括导电层和基膜；所述导电层和基膜构成导电膜；所述基膜为柔性基膜；所述背胶层，设置于所述基膜上与所述导电层相对的一侧，
