Heating module for heating flowing media and method for producing same

The module (1) has an isolation layer arranged between electrodes (3) in an edge region of a disk-shaped positive temperature coefficient (PTC)-element (2). The layer is formed as a temperature-resistant adhesive layer (5) for electrical isolation of the electrodes and for mechanical fixing of the electrodes with each other. The electrodes have contact surfaces (313) from 8/10 of entire surface of the electrodes so that remaining surface of the electrodes secures mechanical connection of the electrodes and ensures permanent contacting of the element in a region of the contact surfaces. An independent claim is also included for a method for producing a heating module.
