Thermal recording head

摘要

A thermal recording head which comprises a plurality of heat-generating resistors; an insulation substrate on which a plurality of separate conductors are mounted to be connected to the heat-generating resistors directly or with diodes interposed therebetween; and a 3-ply conductor holder formed of an insulation sheet, an assembly of common conductors mounted on the insulation sheet at a prescribed interval and an insulation layer deposited on the common conductors with a thickness of 2 to 20 microns, and wherein the insulation layer has openings arranged at a prescribed interval; and the insulation substrate is laminated with the conductor holder with the common conductors connected to the separate conductors.
