Thermal head, and thermal printer equipped with same

To prevent the extension of cracks in a heat storage layer and a protective film. This thermal head (X1) comprises a substrate (7), a heat storage layer (13) which is arranged on one main surface of the substrate (7) so as to be located at an edge (7a) of the substrate (7) and is composed of a glass, an electrode which is formed on the heat storage layer (13) so as to be apart from the edge (7a) of the substrate (7), a heating resistor (9) which is connected to the electrode and is formed on the heat storage layer (13) so as to be apart from the edge (7a) of the substrate (7), a first coating layer (24) which is formed on the electrode and the heating resistor (9), and a protective film (25) which is formed on the first coating layer (24), wherein the first coating layer (24) spreads over the electrode and the heating resistor (9) on the heat storage layer (13); and extends to the edge (7a) of the substrate (7), the protective film (25) is formed on a part of the first coating layer (24) which is located on t
