Abstract
A thermal head in which power durability of the heat-generating element is improved and a thermal printer including the same. A thermal head according to an embodiment includes a substrate, electrodes disposed in a pair on the substrate, a heat-generating element disposed between the electrodes and connecting the electrodes to one another, an electric resistor layer disposed below the electrodes, and a protection film disposed on the electrodes and the heat-generating element. The electrodes include a first electrode and a second electrode electrically connected to the heat-generating element. The heat-generating element and the electric resistor layer each contain at least one metal selected from Al, Cu, Ag, Mo, Y, Nd, Cr, Ni and W, in a region on a protection film side thereof. A content of the metal contained in the heat-generating element is higher than a content of the metal contained in the electric resistor layer disposed below the first electrode.
