<p>PURPOSE:To provide built-in elements of an electron tube and their manufacture not abruptly deteriorated with the mechanical strength of metal terminals during use over a long period by specifying the composition of connecting conductor layers formed on a ceramic insulating substrate mainly made of an aluminum oxide and the metal terminals connected to them. CONSTITUTION:A resistive layer 12 is formed on an insulating substrate 11, and metal terminals 16 are electrically connected to the resistive layer 12 via connecting conductor layers 13. The connecting conductor layers 13 are made of a mixed sintered layer containing palladium, silicon, and titanium, and the metal terminals 16 are made of nickel.</p> |
