Thermal head, thermal printer, and manufacturing method for thermal head

Abstract

To improve printing quality and reduce manufacturing cost, 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 adhesive layer (12) includes a first adhesive layer (12a) laminated on the surface of the supporting substrate (11) and a second adhesive layer (12b) laminated on a surface of the heat storage layer (13). The elastic material constituting the second adhesive layer (12b) is arranged so that the elastic material is in a bonded state with respect to at least a part of the surface of the heat storage layer (13) opposed to the cavity portion (19).
