摘要： A PTC heating device has contact surfaces formed by a metallization, and also has first and second contact elements which are to be assigned different polarity and which are electrically contacted with the contact surfaces. Both of the first and second contact surfaces are circumferentially sealed by a frame that follows the contour of the respective contact surface and that is made of an electrically non-conductive adhesive coating. In the method of making the PTC heating device, the contact surfaces of the PTC element are contacted in an electrically conductive manner with the two contact elements, each of which has a strand an electrically non-conductive adhesive coating following the contour of the contact surfaces. During this contacting, the adhesive coating is displaced in such a manner that both contact surfaces are circumferentially sealed by a frame formed by the adhesive coating.
