<p>A thermal head capable of dissipating heat accumulated in a heat accumulating layer efficiently and achieving clear printing, and a thermal printer including the thermal head are provided. A thermal head includes a substrate (7), a heat accumulating layer (13) disposed on part of the substrate (7), a heat generating portion (9) disposed on the heat accumulating layer (13), an electrode electrically (17, 19, 21) connected to the heat generating portion, a protective layer (25) that covers the heat generating portion (9) and part of the electrode (17, 19), and an insulating layer (27, 29) having thermal conductivity, the insulating layer (27, 29) covering part of a region of the electrode (17, 19, 21) which region is not covered with the protective layer (25). The insulating layer (27, 29) covers part of the protective layer (25) and extends over the heat accumulating layer (13).</p> |
