Abstract
PURPOSE: To lengthen the life of a heat-sensitive recording head as well as raise the quality of printing by forming the shape of a given region on the surface of a glaze layer into a convex shape and also making the distance between th convexed part and a lead layer larger than 10μm.
CONSTITUTION: Usually, a vitreous glaze layer 3 is provided on a base plate 2 of ceramics, etc., and a convexed part 30 is formed on the layer 3. The convexed part 30, serving to form a flattened convexity on the heating and sliding surface of the head, is so formed that a step difference similar to or more than the thickness of lead layers 51 and 53 is formed in the convexity and also the lead layers 51 and 53 are provided on the concaved parts in contact with the convexity 30. In this case, when the distances (a) and (a') between the lead layer end and the glaze layer end are made larger than 10μm, the life of the head and the quality of printing are critically increased by a reason that the unequal temperature gradient in the stepped part is eliminated and heat stress is relaxed.
