ングにより複数の記録電極を形成する。As shown in Japanese Unexamined Patent Application Publication No. 60-214972, the recording head of the current transfer type recording device, which supplies electricity to the thermal transfer ribbon, prints tungsten, molybdenum, or a mixture of tungsten and molybdenum, etc. on a ceramic substrate using a screen printing method. After forming the metallized layer, a plurality of recording electrodes are formed by photoetching.

。また、ガラス質の混在により記録電極の緻密性が低く
、耐久性に乏しい。However, with this method, there is a lot of glass that enters the metallized layer from the substrate during firing, which limits the miniaturization of recording electrodes by photoetching.Additionally, the mixture of glass parts has poor current conduction characteristics, resulting in a decrease in printed image quality. invite,
Further, many of the ceramic materials for the substrate are difficult to metalize, and there is a drawback that the substrate materials are limited. Furthermore, due to the presence of glass, the density of the recording electrode is low, resulting in poor durability.

形成するので、微細化を実現でき、かつ緻密であるから
通電特性も良好なものができる。After forming a negative pattern of a plurality of recording electrodes on the head substrate using photoresist, the recording electrodes are formed by plating, so that miniaturization can be achieved, and since the electrodes are dense, good current conduction characteristics can be achieved.

This eliminates the problem and maintains good current conduction characteristics.
そして、硬質粒子を分散させた複合合金めっきによれば
耐摩耗性を合金めっきよりも更に向上させることができ
、また潤滑性粒子を分散させれば摩耗が減る。Composite alloy plating in which hard particles are dispersed can further improve wear resistance than alloy plating, and dispersion of lubricating particles reduces wear.

A/dm" Then, further, the portion of the tip of the recording electrode 4 other than the end surface 5 that contacts the ribbon was coated with ceramic (commonly known as spinel) 6 made of the same material as the substrate 2 by plasma spraying. As a result, Carbon and the like of the ribbon generated by sliding with the ribbon is no longer deposited between the recording electrodes 4, and good current conduction characteristics are maintained.Furthermore, the adhesion between the recording electrodes 4 and the head substrate 2 is improved, The recording electrode 4 does not peel off, resulting in excellent durability.The ceramic 6 may cover at least the tip of the recording electrode 4, except for the end surface in contact with the ribbon.
