PURPOSE:To increase thermal response, gradation recording property, reduce the irregularity of resistance and allow printing to be performed at high speed and with high quality by forming a conductor electrode for energization on the protruding section of an insulated substrate. CONSTITUTION:Conductor electrodes for energization 3, 4 provided, for allowing a resistor 5 for heat generation to generate heat, in a thermal head are formed in the projecting sections 7 of insulated substrates 1, 2. Consequently, the superior thermal response, gradation recording property and significant electric power saving of each heat-generating dot of the thermal head can be achieved. Thus high-speed and high-quality printing is performed at low cost. |
