Abstract

PURPOSE:To prolong the lifetime of the head and improve the quality of picture by providing an insulation layer so as to contact with a heating body layer selectively excepting for the vicinity of the lateral end part of the heating part of a lead layer in the head for thermal recording having the silicon heating body layer. CONSTITUTION:On a substrate 2 formed of ceramics and the like is provided a glaze layer 3 of glass quality and thereon the heating body layer 4, the lead layers 51 and 53 and an insulation layer 7 are formed. The heating body layer 4 is formed by providing multicrystal thin silicon films in a prescribed arrangement and a pair of lead layers 51 and 53 are connected thereto in opposition at a prescribed interval. The lead layers 51 and 53 may be positioned either above or below the heating body layer 4. The insulation layer 7 is formed of SiO2 and the like and is employed as the negative side. It is formed so as to contact directly with the heating body layer 4 in the region except for the vicinity of the end part on the heating part side of one lead layer 51. By this constitution, the excess of cation on the upper surface of the glaze layer 3 is prevented and the projected difference in level near the end part of the heating part is eliminated.
