Abstract
A heating resistance element component has a supporting substrate, an insulating film laminated on the supporting substrate, heating resistors arranged at intervals on the insulating film, a common wire connected to one end of each of the heating resistors, and individual wires each connected to another end of the each of the of heating resistors. A surface of the supporting substrate is formed with a first concave portion and a second concave portion. The first concave portion is arranged in a region opposed to heating portions of the heating resistors. The second concave portion is arranged at an interval in a vicinity of the first concave portion so that heat generated by the heating portions of the plurality of heating resistors is prevented from flowing into the supporting substrate.
