Abstract

PURPOSE:To prevent the deterioration of lifetime accompanying the local impression of excessive stress caused by the difference in level in the end part on the side of the heating part of a lead layer by forming a high-resistance silicon layer in a prescribed region in the thermal recording head having a silicon heating body layer on a glaze layer. CONSTITUTION:In the thermal recording head 1 formed of the glaze layer 3 on the base plate 2, of a silicon heating body layer 4 thereon and of the lead layers 51 and 53 contacting with the heating body layer 4, and, in addition, facing each other at a prescribed gap, the high-resistance silicon layer 7 contacting directly with the silicon heating body layer 4 is formed in the prescribed region within the gap between the facing lead layers 51 and 53 except for the prescribed region near the end part on the side of the heating part of, at least, one lead layer. The region where the high-resistance silicon layer 7 is formed is the area excepting those directly below the end part on the side of the heating part of one lead layer 51 employed as a negative side and in the above and vicinity thereof. By the way, when the high-resistance silicon layer 7 is provided only in the prescribed region within the gap between the facing lead layers 51 and 53, the breakage of the laminate body is prevented more effectively.
