Thermal head |
摘要 |
A thermal head of the present invention is composed of a substrate, a resistive heater element formed on the substrate, and electrically conductive members to supply electric power to the resistive heater element, wherein the resistive heater element contains a metal boride as the principal constituent. The thermal head of this construction is capable of selecting its resistivity to a high value and causing a large electric current to flow in the form of short pulses for the purpose of high speed printing, hence it is stable against repetitive pulse applications over a long period of time.
