<p>A thermal head comprises a heat accumulating member (2) disposed on a substrate (1), a plurality of heating resistors (3) juxtaposed on the heat accumulating member (2) in a manner to be spaced from each other, electrodes (4) for supplying electric power to the heating resistors (3), and a protective member (5) for preventing oxidation and wear of the heating resistors (3) and the electrodes (4), these constituents being formed as layers.</p><p>When the electric power is supplied to the electrodes (4), heat is generated by a heating portion (3a) of the heating resistor (3) corresponding to the electrodes (4), and it is transmitted to a head surface (6a) via a thermally conductive member (7) disposed in a printing dot portion (6a) of the protective member (5). The heat from the printing dot portion (6a) is used for effecting printing on a medium to-be-recorded through a thermosensitive sheet (9) which lies in contact with the head surface (6a).</p> |
