ABSTRACT:
A ceramic substrate which comprises a ceramic base material having porosity of not more than 5% and surface roughness R.sub.max of not larger than 0.1 .mu.m, and an amorphous aluminum oxide film having thickness of 1 to 50 .mu.m formed on a surface of said ceramic base material, has high reliability and can be easily surface finished with high accuracy and can be used to form a thin film magnetic circuit.
