Abstract

PURPOSE:To obtain a thermal head with reduced power consumption during thermal recording and excellent recording quality by a method wherein an electrode conductor is printed on an unbaked insulative base plate and after the printed base plate is bent into a curved surface form, baking is carried out. CONSTITUTION:On an upper surface of an unbaked flat plate like insulative base plate 21, plural electrode conductors 22a, 22b are arranged in a desired shape by screen printing or the like to form a conductor pattern. Subsequently, the insulative base plate 21 having the conductor pattern formed thereon is bent so as to form a central part thereof into a convex curved surface form and, thereafter, the resultant processed plate is baked at about 1,300-1,800 deg.C in a reductive atmosphere. Next, to a position convering an upper surface of an end part faced to the conductors 22a, 22b, a resistor 23 is formed by screen printing or vapor deposition. Because thus constituted thermal head 20 forms one point contact with a heat sensitive recording paper 14, heat is effectively conducted and recording quality can be enhanced.
