The invention provides a heat-emitting electrically-conductive plastic adhesive tape. The heat-emitting electrically-conductive plastic adhesive tape is composed of a substrate, an electrically-conductive adhesive, a heat-emitting electrically-conductive sludge and a plastic skin. The substrate of the heat-emitting electrically-conductive plastic adhesive tape is a 0.1-0.5mm-thick aluminum foil, one side of the aluminum foil is coated with the 0.1-0.2mm-thick acrylate adhesive, the other side is coated with the 0.1-1mm-thick electrically-conductive sludge, the inside of the electrically-conductive sludge is pressurized into a power connection, and the surface is coated with the plastic skin; and in the use process, the plastic skin is peeled. The plastic adhesive tape is simple to use and convenient to operate, can be attached to the place in need of heating, and can be used by electrifying; and the plastic adhesive tape has the advantages of high electrifying heating speed, high energy utilization ratio, building lot saving, resource saving and high safety.
