Abstract
In order to provide a manufacturing method for a heating resistor element component, with which an insulating film (undercoat) can be easily handled, damage caused in the insulating film can be reduced, and a high yield can be ensured, the manufacturing method comprises the steps of: processing, on a surface of a supporting substrate (2), a plurality of concave portions (8) each forming a hollow portion (7) at intervals; processing, on the surface of the supporting substrate (2), a concave part (10) for each region straddling the plurality of concave portions (8) in an arrangement direction of the concave portions (8); placing an insulating film (3) made of sheet glass in each concave part (10); and bonding the insulating film (3) to the supporting substrate (2).
