ABSTRACT:
A thermal head is provided with a heat accumulating member disposed on a substrate, a plurality of heating resistors juxtaposed on the heat accumulating member in a manner to be spaced from each other, electrodes for supplying electric power to the heating resistors, and a protective member for preventing oxidation and wear of the heating resistors and the electrodes, these constituents being formed as layers. When the electric power is supplied to the electrodes, heat is generated by a heating portion of the heating resistor corresponding to the electrodes, and it is transmitted to a head surface via a thermally conductive member disposed in a printing dot portion of the protective member. The heat from the printing dot portion is used for effecting printing on a medium to-be-recorded through a thermosensitive sheet which lies in contact with the head surface.
