Abstract

PURPOSE:To improve the quality of a picture by raising the linear density and also improve the thermal transmission efficiency and responsiveness by burying a heater- rsistor layer in a groove formed on the surface of a substrate of a thermal head so as to reduce the scattering of the heater-resistor layer. CONSTITUTION:After a heater-resistor 22 being buried in a groove 20 formed on an insulating substrate 21 and the surfaces of both substrate 21 and the heater- resistor 22 being formed into one and the smae surface, an electrical conductor 23 is joined electrically with the heater-resistor 22 by the method for preparing a thin film. Then, by employing the hard material with excellent thermal conductivity (e.g. Sic), an anti-abrasion layer 16 is laminated on the heater-resistor 22 and the conductor 23. In addition, so as to check the diffusion of heat from the heater- resistor 22 to the substrate 21, heat-intercepting layers 24 may be formed on both lateral surfaces of the heater-resistor 22 before buruing the heater-resistor in the groove 20.
