Abstract
To improve print quality, a plurality of heating resistors (14) are arranged with spaces therebetween on a heat storage layer (13) laminated on a surface of a supporting substrate (11) via an adhesive layer (12) made of an elastic material. A cavity portion (19) is formed at a region between the supporting substrate (11) and the heat storage layer (13), the region being opposed to a heat generating portion of each of the plurality of heating resistors (14). The elastic material constituting the adhesive layer (12) is arranged so that the elastic material is in a bonded state with respect to at least a part of a surface of the heat storage layer (13) opposed to the cavity portion (19).
