Thermal head, manufacturing method therefor, and printer

摘要

Provided is a thermal head with enhanced strength and improved thermal efficiency including a cavity portion formed therein at a position corresponding to a heating resistor. Employed is a thermal head (1) including: a support substrate (3) including a concave portion (2) formed in its front surface; an upper substrate (5) bonded in a stacked state to the front surface of the support substrate (3); a heating resistor (7) provided on the front surface of the upper substrate (5) at a position corresponding to the concave portion (2); a pair of electrode portions (8) provided on both sides of the heating resistor (7); and a concave portion (20) formed in the front surface of the upper substrate (5) on a side of the pair of electrode portions (8), the concave portion being provided between the pair of electrode portions (8).
