Abstract: The invention relates to a heating and/or cooling device (10) for delivering heating and/or cooling energy to the body of a living being (28). The heating and/or cooling device (10) comprises a heating and/or cooling pad (12) which can be connected to the body of the person (28). The heating and/or cooling pad has an upper face (122) and a lower face (121), and an adhesive surface (1210) is provided on the lower face (121) for attaching the heating and/or cooling pad (12) to the surface of the skin of the person (28). The heating and/or cooling pad comprises at least one heating and/or cooling element (26) by means of which electrical energy output by an electrical energy source (22) can be converted into heating and/or cooling energy. The heating and/or cooling device (10) further comprises a control unit (14) which is provided for fixedly or detachably accommodating the energy source (22) and has a signal processor (16).
