Abstract
PURPOSE: To improve a heat insulating property and a flat property and to form a thick film type thermosensitive recording head having high efficiency at low cost by a method wherein a groove, width thereof is wider than the width of a heat generating resistor, is made up on a substrate corresponding to a lower section of the resistor, and a dielectric layer with double layer structure is built up so as to bury the groove.
CONSTITUTION: A groove 7, width thereof is wider than the width of a heat generating resistor 3, is formed on a radiating substrate (alumina substrate) 1. The groove 7 is buried by a dielectric layer (heat insulating layer) 2, a dielectric layer 2' is further made up on the layer, a flat property of the surface is improved, and a pair of opposing conductors 6, 6' for electrodes and the resistor 3 are mounted on the layer 2', thus forming a thermosensitive recording head.
