Heating resistor element component

摘要

To improve heating efficiency and printing quality, a heating resistor element component (4) includes a plurality of heating resistors (14) arranged with intervals on a heat storage layer (13) laminated on a supporting substrate (11) through an intermediation of an adhesive layer (12), in which: the adhesive layer (12) includes an adhesive (12a) for bonding one surface of the supporting substrate (11) and another surface of the heat storage layer (13), and a plurality of gap members (12b) kneaded in the adhesive (12a), for keeping a distance between the one surface of the supporting substrate (11) and the another surface of the heat storage layer (13) constant; and a cavity portion (19) is formed in a region of the adhesive layer (12), the region being opposed to a heating portion of the heating resistor (14).
