ABSTRACT:
A method of simultaneously producing a plurality of thermal heads having a ridge-shaped glaze structure uses first and second glass pastes, the second glass paste having a higher softening temperature than the first glass paste. The first glass paste is printed on a substrate in a pattern having a plurality of adjacent slit-shaped openings in parallel. Next, the second glass paste is printed in a pattern having independent bands which cover the openings. The first and second glass pastes are melted and hardened simultaneously by heat treatment so as to form the ridge-shaped glaze structure. A plurality of isolated individual resistors are formed linearly along the crest of the ridge-shaped glaze structure, and a plurality of isolated individual traces are formed which connect at one end to each of the resistors. Lastly, the substrate is divided along separation lines into a plurality of thermal heads having a ridge-shaped glaze structure.
