Thermal Head and Method of Manufacturing the same, and Printer

摘要

Adopted is a thermal head (1), including: a support substrate (3) including a concave portion (2) formed in a front surface thereof; an upper substrate (5), which is bonded in a stacked state to the front surface of the support substrate (3) and includes a convex portion (20) formed at a position corresponding to the concave portion (2); a heating resistor (7) provided on a front surface of the upper substrate (5) at a position straddling the convex portion (20); and a pair of electrodes (8) provided on both sides of the heating resistor (7), in which at least one of the pair of electrodes (8) include: a thin portion (18), which is connected to the heating resistor (7) in a region corresponding to the concave portion (2); and a thick portion (16), which is connected to the heating resistor (7) and is formed thicker than the thin portion (18).
