Abstract

PURPOSE:To improve printing quality and to elongate the life of a heater by providing regions wherein conducting material does not exist at the contact parts of the heater and the electrodes in the thermal head, and equalizing the temperature distribution. CONSTITUTION:In the heating part of the thermal head comprising the heater 1, the electrodes 2, and the like, the regions 4 wherein the conducting material does not exist are provided at the contact parts of the heater 1 and the electrodes 2. In this way, the current density at the central part of the heater 1 becomes low, the thermal concentration to the central part of the heater 1 in printing is avoided, the temperature at the central part becomes relatively low, and the high temperature region is dispersed. Therefore the heating temperature is equalized or dispersed, stable printing quality is obtained, thermal impact is not concentrated on one part at the time of printing, and the life of the heater is elongated.
