Zusammenfassung:	To provide a thermal head in which separation of a protective layer is unlikely to occur. A thermal head X1 includes a substrate 7, a heat-generating portion 9 disposed on the substrate 7, electrodes 17 and 19 disposed on the substrate 7 and electrically connected to the heat-generating portion 9, and a protective layer 25 which covers the heat-generating portion 9 and part of the electrodes 17 and 19. The electrodes 17 and 19 each includes a first region R1 which lies below a depth of 150 nm from the surface 17e or 19e located on the protective layer 25 side, and the first region R1 contains oxygen. It is possible to suppress separation of each of the electrodes 17 and 19 from the protective layer 25.
