Abstract:
A thermal head includes: a substrate; a heat storage layer disposed on the substrate; a heat-generating section disposed on the heat storage layer; an electrode electrically connected to the heat-generating section; a protection layer which coats the heat-generating section and a part of the electrode; and a first coating layer which coats a part of the protection layer and is disposed downstream in a transportation direction of a recording medium, with respect to the heat-generating section, the first coating layer including a first protrusion protruding towards a recording medium side, an end on a heat-generating section side of the first coating layer being positioned between the first protrusion and the heat-generating section, and the end on the heat-generating section side of the first coating layer being positioned in a range of L/2 from the heat-generating section, in which L is a distance between the heat-generating section and the first protrusion.
