Title: HEATING PATCH, AND WARMING DEVICE FOR SKIN CARE COMPRISING SAME
Abstract:
Provided is a heating patch. The heating patch according to an illustrative embodiment of the present invention comprises: a flexible plate-shaped base substrate; an electrode part including a pair of lead electrodes and pairs of branch electrodes, wherein the lead electrodes are formed in the longitudinal direction on at least one surface of the base substrate and are disposed spaced apart from each other in the width direction of the base substrate, and the branch electrodes respectively extend from the pair of lead electrodes in the width direction of the base substrate in such a way as to overlap with each other for a certain length without being electrically connected to each other; a heating part having a predetermined area so as to be able to electrically connect the pairs of branch electrodes and at the same time generate heat upon being supplied with power, the heating part including a conductive heating material and being disposed in an overlapping region between the pairs of branch electrodes that face each other; and a pair of cover members disposed on both surfaces of the base substrate to prevent the electrode part and the heating part from being exposed to the outside. The heating part comprises a plurality of heating parts disposed spaced apart at predetermined intervals in the longitudinal direction of the base substrate, and the plurality of heating parts are formed so as to have the same resistance.
