Abstract: A PTC heating module may include at least one cuboid PTC thermistor element with two opposing main surfaces, which may be connected to one another via two opposing lateral surfaces. The PTC heating module may also include two contact elements each lying against one of the lateral surfaces and via which the PTC thermistor element may be electrically contactable, a housing in which the at PTC thermistor element and the contact elements may be arranged, and two insulating boards each lying against one of the main surfaces and electrically insulating the PTC thermistor element from the housing and connecting the PTC thermistor element to the housing in a heat-transferring manner. Each contact element may be electroconductively fixed on one side on one of the lateral surfaces and on another side on one of two contacting tracks, each of which may be arranged on one of the insulating boards.
