Abstract

PURPOSE: To easily record in multiple gradations by so forming a glazed layer as to be thick at a part of a heat generating resistor connected to an electrode having a narrower effective width than the resistor and thin at the substantially central part of the heat generating resistor.
CONSTITUTION: In a thermal head 10, a glazed layer 16 is formed as a heat accumulator on an alumina board 17, a resistance layer 15, electrode layers 12, 13 are further formed thereon, partly cut out to form the electrodes 12, 13 and a heat generating element 11, which are covered with a wear resistant layer 14. Here, the width of the electrode at the connecting part of the heat generating element 11 to the electrodes 12, 13 is narrow, and the glazed layer 16 corresponding to the width of the electrode is so formed as to protrude at the connecting part of the heat generating element 11 to the electrodes 12, 13 as a vertex. Accordingly, the shape of the heat generating element 11 is formed in a protruding shape to remarkably concentrate its heat generating temperature. Thus, a recording in multiple gradations can be easily realized.
