THERMAL HEAD AND THERMAL PRINTER PROVIDED WITH SAME

摘要

[Problem] To provide a thermal head with which the occurrence of protective layer peeling can be reduced, and a thermal printer provided with same. [Solution] The thermal head (X1) is provided with: a substrate (7); an electrode provided on the substrate (7); an electrical resistor (15) that is connected to the electrode and a portion of which functions as a heat-generating part (9); and a protective layer (25) provided on the electrode and on the heat-generating part (9). The protective layer (25) comprises a first layer (25A) containing a silicon nitride or silicone oxide, and a second layer (25b) that is provided on the first layer (25A) and contains a tantalum oxide and a silicon oxynitride.
