摘要：
To reduce a plate thickness of an insulating film, a heating resistor element component is provided, which includes: a supporting substrate; an insulating film disposed on a surface of the supporting substrate; a plurality of heating resistors arranged at intervals on the insulating film; a common wire connected to one end of each of the plurality of heating resistors; and individual wires each connected to another end of each of the plurality of heating resistors, in which: the surface of the supporting substrate is provided with a concave portion in a region thereof, the region being opposed to heating portions of the plurality of heating resistors; and when the insulating film is superimposed on the supporting substrate, the insulating film includes a heterogeneous phase formed through irradiation of a phemtosecond laser at least in a region thereof, the region being opposed to the concave portion.
