Abstract
A thick film complex electronic component mounted on a substrate including an inductance, capacitance and/or resistance by a conductive film and a magnetic film on a ceramic substrate is improved by novel magnetic film. The magnetic film is produced by depositing paste of a raw material of ferrite on the substrate, and the paste together with the substrate are sintered at a relatively low temperature in the range of 600.degree. C. and 1200.degree. C. The present magnetic film which is sintered after the raw material of ferrite is deposited on the ceramic substrate has higher permeability and is mechanically stronger.
