Abstract:
1. A circuit component mounting device, comprising: a substrate; two conductor members provide on parts of the substrate; a circuit component which is provided on the two conductor members and includes two electrodes in contact with the conductor members and a main body interposed between the two conductor members; a solder which allows the conductor members and the circuit component to adhere to each other; and an insulator which includes grains and is filled in a region interposed between the two conductor members in a region between the substrate and the circuit component, wherein the conductor members are comprised of a base metal pattern which is made of a Cu layer and a Ni layer and a plated pattern which is made of a Cu layer, a Ni layer and a Au layer and formed on the base metal pattern, the base metal pattern is formed at the same time when a circuit pattern is formed on another part of the substrate, and height of the conductor members is three times or more than an average grain diameter of the grains of the insulator.
