Abstract
Provided is a heating patch. The heating patch includes: a flexible plate-shaped base substrate; an electrode portion including a pair of lead electrodes formed on at least one surface of the base substrate along a longitudinal direction to be spaced apart along a width direction of the base substrate, and a pair of branch electrodes extending from the lead electrodes along the width direction of the base substrate to be not electrically connected to each other and to be overlapped with each other; a heating portion including a conductive heating material disposed in an overlapped part between the branch electrodes which have a predetermined area and face each other to generate heat while conducting the pair of branch electrodes to each other; and a pair of cover members disposed on both sides of the base substrate to prevent the electrode portion and the heating portion from being exposed externally.
