    摘要: A ceramic circuit board comprises a ceramic substrate having a glaze film formed thereon, the glaze film being overlaid with a functional thin film such as a ferromagnetic film serving as a magnetic sensor, for example. The ceramic substrate is made of a low-firing ceramic material such as a glass ceramic material which can be sintered at a temperature below 1000.degree. C. by co-firing with the glaze film. Preferably, the ceramic substrate has a recess on its top surface, and the glaze film is embedded in the recess such that the difference in level between the ceramic substrate and the glaze film is 20 .mu.m or less. The ceramic circuit board can be produced by preparing a plurality of ceramic green sheets from a low-firing ceramic material, laminating the ceramic green sheets after a through-hole or indentation is formed in the uppermost sheet, thereby forming a multilayer ceramic green substrate having a recess on its top surface, filling the recess with a glaze-forming glass material to such a height that the difference in level between the ceramic substrate and the glaze film formed after firing is 20 .mu.m or less, and co-firing the ceramic green substrate and the glaze-forming glass material at a temperature below 1000.degree. C.

    摘要: A ceramic circuit substrate providing a circuit pattern with a fine line as well as high accuracy for positioning the circuit pattern and a method of producing the ceramic circuit substrate. An alumina layer that is green containing an alumina that is not sintered at a temperature ranging from 800.degree. to 1000.degree. C. is applied on a surface of a ceramic green sheet containing glass and then fired at a temperature ranging from 800.degree. to 1000.degree. C. The ceramic green sheet is sintered into a sintered ceramic substrate. A porous alumina layer is formed on a surface of the sintered ceramic substrate. The glass contained in the sintered ceramic substrate is caused to flow to the inside of the porous alumina layer so that the part of the porous alumina layer filled with the glass is bonded to the sintered ceramic substrate. The part of the porous alumina layer not filled with the glass is removed, wherein the porous alumina layer remaining on the sintered ceramic substrate after the removing has a thickness of 10 .mu.m or less. A paste for forming the circuit pattern is printed on a surface of the part of the porous alumina layer that has been bonded to the sintered ceramic substrate for heating.
