PURPOSE:To make it possible to perform thermal recording with high printing quality generating no deterioration of printing quality over a long time by certainly performing the contact with thermal recording paper, by sufficiently protruding a heat generating dot part. CONSTITUTION:A thermal head consists of a substrate 1, a glaze layer 2, an under coal layer 3, a heat generating resistor layer 4, a conductor electrode layer 5 and an oxidation inhibiting layer 6. A first metal layer 7 and a second layer 8 are provided only at the position corresponding to the heat generating dot part 12 of the heat generating resistor layer 4. The first metal layer 7 is an extremely thin metal layer and a second metal layer 8 is selectively formed only on the first metal layer 7 being a base. The thickness of the second metal layer 8 may set to a degree correcting the concaved shape of the heat generating dot part 12. An abrasion resistant layer 9 covers the whole of the thermal head after the first metal layer 7 and the second metal layer 8 were formed. |
