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

Abstract

Provided is a thermal head that is high in durability and reliability with increased printing efficiency as well as increased manufacturing yields. The thermal head (1) includes: a support substrate (12) including a concave portion (23) having an opening portion (23a) formed in a surface of the support substrate (12); an upper substrate (14) having an external dimension which is smaller than an external dimension of the support substrate (12) and is slightly larger than an external dimension of the opening portion (23a), for closing the opening portion (23a) when bonded to the surface of the support substrate (12) in a stacked state; and a heating resistor (15) formed on a surface of the upper substrate (14) in a position opposed to the concave portion (23) of the support substrate (12).

Dependencies are inferred from the claim text.
