Abstract

PURPOSE:To make effective use of the respective advantages that thin film system and thick film system possess by making heating element parts by the thin film system and common lead multilayer wiring parts and driver multilayer wiring parts by the thick film system. CONSTITUTION:In the thermal head provided with the heating element part consisting of a multiplicity of heating resistance elements and mulilayer wiring parts for high speed driving of the heating resistance elements by dividing them to blocks on a high resistance substrate; a thin film substrate 10 formed with heating resistance elements 8 and electrodes 9 by a thin film system, a thick film substrate 11 formed with the mount portions of separating diodes 2 on ceramics, common lead multilayer wiring part 3, common lead terminal part 4 on ceramics by a thick film system and a thick film substrate 12 formed with the mount portions of the separating diodes 2, driver multilayer wiring part 5, driver terminal part 6 by a thick film system on ceramics are disposed and bonded by means of adhesives on a heat sink 7 composed of metal of good heat conductivity as a substrate.
