To improve heat generating efficiency and printing 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 section (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 cavity section (19) includes a concave portion (20) formed in the surface of the supporting substrate (11) and the heat storage layer (13) in which the concave portion (20) is closed and the surface thereof is exposed to the cavity section (19).
