Abstract

PURPOSE:To prevent the diffusion of electrode material into heating resistor by making up the electric material of a heat-sensitive recording head of an intermetallic compound which is in solid state at the heating temperature of a heating resistor used and has a specific resistance smaller than the heating resistor. CONSTITUTION:An intermetallic compound to be used as a material for an electrode 6 must meet the two requirements, having a solidity at the heating temperature of a heating resistor 5 and a specific resistance smaller than that of the constituent mateial of the heating resistor 5. Of intermetallic compounds, NiAl has smallest specific resistance and is most suitable for an material for electrode. Thus, the diffusion of the electrode materal into the heating resistor can be prevented, whereby preventing the lowering or local variation of the resistance value of the heating resistor due to the influence of the electrode material.
