ABSTRACT:
In a thermal head comprising a plurality of heat-generating elements formed on a glaze layer on a substrate, grooves extending to the midway of the glaze layer in the thickness direction of the glaze layer and having a depth of 0.3 to 30 .mu.m are formed in the surface portion of the glaze layer between every two adjacent heat-generating elements. This thermal head is improved in both the rising and falling response characteristics of the heat-generating temperature by the presence of these grooves, and sharp images having a high resolving power can be obtained.
