In a thermal print head (10), a partial glazed layer (13) has a width of 0. 1 to 0. 4 mm and a height of 15 to 25 mu m. With the partial glazed layer (13) of this size, since the amount of accumulated heat is reduced, no trailing phenomenon would arise so as to improve the printing quality. It is also advantageous that no defective product will be manufactured because the glazed layer (13) is not too small, with less energy consumption. As a result, a high-quality printing operation can be maintained even during such high-speed printing as not exceeding 1 ms per one line. <IMAGE> |
