Abstract
Abstract An electric component part has its lead terminals (55) bent in thickness directions in a middle section thereof at at least two positions so that a step section (l4b) virtually in parallel to the bottom of a circuit substrate (ll) is formed with the intention of absorbing the external force applied to the part by changing the shape of the lead terminals (55). Increase in the part layout area due to the formation of the horizontal step section can be avoided, when necessary, by shifting the terminal lead out position on the component part inward thereby to minimize the jetty dimensions.
