PURPOSE:To obtain a ceramic wiring board mounting a semiconductor element which board can normally operate the semiconductor element for a long term, by reducing the change of resistance value of a resistor, and restraining waveform perturbation to a minimum which is caused by reflection of a signal travelling a metallized wiring layer. CONSTITUTION:In a ceramic wiring board wherein metallized wiring layers 5a, 5b, 5c and a resistoe 8 are stuck and formed on an insulative substratum 1, the resistor 8 is formed of 100 pts.wt. of metal powder, 10-100 pts.wt. of insulator powder, and 1.0-15.0 pts.wt. of nickel. The metal powder contains 10-60wt.% tungsten powder and 40-90wt.% rhenium powder. |
