Abstract
A thermal head which is capable of reducing heat concentration on heat generation portions, and a thermal printer provided with the thermal head are provided. A thermal head includes a substrate; a plurality of heat generation portions which are disposed aligned on the substrate; electrodes which are electrically connected to the heat generation portions; and a protection layer which coats the heat generation portions and a part of the respective electrodes. The protection layer includes a first protection layer which is disposed on the heat generation portions and a second protection layer which is disposed on the first protection layer and has a higher thermal conductivity than that of the first protection layer. A width of the second protection layer is larger than that of the first protection layer when seen in an arrangement direction of the heat generation portions.
