  • Thermal head and method of manufacturing the same
    Patent number: 4772520
    Abstract: This invention discloses a thermal head having a resistive layer of a thin Ta-Si-O film containing more than 45 mol % and at most 75 mol % of a silicon oxide in terms of SiO.sub.2, and a method of manufacturing a thermal head by sputtering a sintered target in vacuum atmosphere at an argon gas partial pressure of 10.times.10.sup.-3 Torr to 80.times.10.sup.-3 Torr so as to obtain the resistive layer.
