Provided is a thermal head including an intermediate layer between a support substrate and an upper substrate, which is capable of suppressing heat dissipation toward the support substrate while maintaining printing quality. Employed is a thermal head (1) including: an upper substrate (5); a support substrate (3) bonded in a stacked state on one surface side of the upper substrate (5); a heating resistor (7) provided on another surface side of the upper substrate (5); and an intermediate layer (6) including a concave portion that forms a cavity portion (4) in a region corresponding to the heating resistor (7), the intermediate layer (6) being provided between the upper substrate (5) and the support substrate (3), in which the intermediate layer (6) is formed of a plate-shaped glass material having a lower melting point than melting points of the upper substrate (5) and the support substrate (3). |
