Abstract
PURPOSE: To obtain the thermal head having high efficiency and long lifetime by lessening the sheet resistance value of the heating part (a part held between a pair of opposed electrodes) of a heating resistor at the central part thereof and thereby uniformalizing the distribution of temperature of the heating part.
CONSTITUTION: A pair of electrodes 3 and 4 are provided in opposition to each other on a heating resistor layer 2 provided on an insulated substrate 1 and thereby the heating part 2' is formed between two electrodes, and further thereon an abrasion resisting layer 5 covering the whole surface is provided. In the thermal head thus formed, the sheet resistance value is lessened by attaching a low-resistance layer 6 on the central part between the electrodes 3 and 4 of the abovementioned heating part 2'. In the formation of the aforesaid low-resistance layer 6, the electrodes 3 and 4 are formed conventionally by laminating upper-layer electrodes 3b and 4b of an Au film on lower-layer electrodes 3a and 4a of a Cr film, and on the occassion of formation of the lower-layer electrodes, it is convenient to take a method wherein the low-resistance layer is formed simultaneously and of the same material.
