Abstract
A thermal head includes a substrate; a plurality of driver ICs configured to be arranged in a main scanning direction; a heater element configured to include a heat storage layer, a heating resistor layer which is made of a plurality of pairs of effective heating portions, and an electrode layer which is patterned to supply electricity to the heating resistor layer; and a protective layer configured to cover a surface of the heater element, wherein the folded electrode is formed by adjusting an area thereof such that a heat distribution of each heating resistor becomes uniform. In such a thermal head, the number of manufacturing processes or the cost does not increase and a heat distribution becomes uniform, so that a good printing result having good a degree of gloss and image can be obtained.
