    摘要： A heater device comprises a supporting body (5) and a plurality of heating elements in the supporting body (5). Each heating element includes a first electrode (14), a second electrode (15), and a material having a PTC effect (16) arranger at least in part between the two electrodes (14, 15). The first electrodes (14), respectively the second electrodes (15), are set at a distance apart in the supporting body (5), with the first electrodes (14) generally parallel to and facing the second electrodes (15). The first electrodes (14) are connected to a first common electrical conductor element (17), and the second electrodes (15) are connected to a second common electrical conductor element (18), and the material having a PTC effect (16) comprises a plastic-based or polymeric-based material moulded or overmoulded at least in part between facing surfaces of the first and second electrodes (14, 15). The supporting body (5) is formed at least in part with a plastic material overmoulded at least in part on the first shaped lamina (19), on the second shaped lamina (20), and on the material having a PTC effect (16).
