Abstract: PROBLEM TO BE SOLVED: To provide a ceramic circuit board which has a conductor film and a minute-area resistor film of precise dimensions formed on a ceramic board and also provide a manufacturing method thereof. SOLUTION: A ceramic circuit board is manufactured by screen-printing conductor paste and resistor paste on a ceramic green sheet 1a and baking them.

The resistor paste is prevented from bleeding in the width direction by a pair of the dams 3a and thereby the resistor film 4 of high dimensional accuracy can be formed. Especially, the thickness of the dams 3a are made smaller than that of the resistor film 4a, but not excessively smaller in the balance between the resistor film 4a and the dams 3a. Therefore, the resistor film 4 of high dimensional accuracy can be efficiently formed with good reproducibility.
