Abstract: A thermal head includes a substrate; a plurality of heat generating portions; a common electrode disposed on the substrate and electrically connected to the plurality of heat generating portions; a plurality of individual electrodes disposed on the substrate and each electrically connected to a corresponding one of the plurality of heat generating portions; a first insulation layer disposed on the heat generating portions, a part of the common electrode, and a part of the individual electrodes; a second insulation layer located adjacent to the first insulation layer and disposed on a part of the individual electrodes; and a static removing layer disposed on the first insulation layer and grounded. The static removing layer includes a first portion disposed on an upper surface of the first insulation layer and a second portion electrically connected to the first portion and disposed on an upper surface of the second insulation layer.

Abstract: Problem: To provide a thermal head in which separation of a protective layer is unlikely to occur.Solution: 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 include 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.
