The invention relates to an electric heating device, especially for heating or air-conditioning equipment of a motor vehicle. The electric heating device has a heating assembly having a plurality of electric heating elements, and the electric heating element has a heating component and an electrical contact component in electrical contact with the heating component. The heating assembly has a plurality of heat dissipating elements that are in thermal connection with the heating elements to transfer heat from the heating elements to a medium flowing through the heat dissipation elements. Each heating component has two opposite wide surfaces and two opposite narrow surfaces. Each electrical contact component is in contact with a corresponding heating component on one of the opposite narrow surfaces, and the corresponding electrical contact component is also overlapped with the heating component on the corresponding wide surface. An electrical insulator is provided between each electricalcontact member and the corresponding wide surface.
