Abstract
A heater element plated on a dielectric substrate through electroless plating process provides an excellent thermal head for thermally printing on a paper. Said heater element composes of nickel, one of phosphorus and boron, and some minor additive agent. That additive agent is one of tungsten and molybdenum by 2-10 weight %. Because of the addition of the additive agent, the life time and heat stress characteristics of a thermal head are considerably improved.
