<p>The device has a heat-generating element (1) comprising a positive temperature coefficient-heating element (2), and conducting lines lying at sides of the heating element for feeding current to the heating element. Heat-delivering elements form counter surfaces for contacting the heat-generating element. One of the conducting lines has contact projections (6.1, 6.2) that project above a contact surface for the heating element, where the contact surface is formed by the conducting lines. The conducting lines comprise metal strips (4.1, 4.2) that are fastened to a housing.</p> |
