意を払わなければならない。Problems to be Solved by the Invention The temperature distribution in the heat generating portion of such a thermal head is not broad in the current direction along the arrangement of the electrode metals, but is sharp in the direction perpendicular to the current direction. The cause of this is the large amount of heat diffusion along the electrode metal, which not only makes recording energy inefficient, but also makes it difficult to obtain optimal printing characteristics in the sub-scanning direction (at right angles to the heating element array) when using a line head. Great care must be taken in controlling the feeding of the recording paper in both directions.

も一部を化合物伝導体で形成する。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention has a heating resistor, M for feeding power thereto, a pole, the heating resistor, and the 'rM, on an insulating substrate. In the thermal head provided with an abrasion resistant layer provided as an abrasion resistant layer, at least a portion of the electrode is formed of a compound conductor.
作 用
電極金属は熱拡散係数が小さいため５発熱抵抗体で発生

る。Since the working electrode metal has a small thermal diffusion coefficient, the heat generated by the heat generating resistor 5 is difficult to diffuse toward the electrode, making it possible to provide a thermal head with sharp temperature distribution and excellent thermal efficiency.
