Through an improvement of module size increase due to mounting a single passive element on a substrate and an increase in the mounting cost, to provide a highly reliable, high performance and small sized electronic circuit component which permits to integrate a variety of electronic parts such as capacitors, inductors and resistors in a high density with low cost.The electronic circuit component comprises an insulator substrate, a plurality of electrodes having different areas provided on the insulator substrate, one or more elements selected from a capacitor element of dielectric material sandwiched between the electrodes, an inductor element and resistor element, a metal wiring connecting the elements, a metal terminal part of a part of the metal wiring and an organic insulator material covering the elements and the circumference of the metal wiring portion excluding the metal terminal portion.
