Abstract

PURPOSE: To reduce the rejection rate of objective articles by forming a crossover insulating layer simultaneously with forming a protective layer on a heating resistor layer.
CONSTITUTION: A heating resistor layer 2 consisting of a Ta film or the like and a feeder conductor layer (a lower conductor) 3 consisting of NiCr-Au or the like are formed in desired patterns on a substrate 1 of a ceramic or the like, and a protective layer 4 consisting of SiO2-Ta2O5 or the like is formed on the region including the resistor layer 2 and the periphery thereof. Simultaneously, a crossover insulating layer 5 also consisting of SiO2-Ta2O5 or the like is formed in regions on the substrate 1 other than said region, while leaving belt-shaped conductor contact regions 6, 7 on both sides of the layer 5. Then, a crossover conductor (an upper conductor) 8 consisting of NiCr-Au or the like is provided on the insulating layer 5 in such a manner that it is connected to the lower conductor 3 through the conductor contact regions 6, 7.
