ABSTRACT:
A radial lead type electronic component includes a couple of plate-type lead terminals projecting from a protective resin member in the same direction. These lead terminals are provided with inclined edges, which make the body portions gradually narrowed toward leg portions, in leg-side edges of body portions. Among inclined edges, inclinations .theta..sub.1 of the outer ones with respect to the leg-projecting direction are greater than inclinations .theta..sub.2 of the inner ones with respect to the same direction. Thus, the electronic component is relieved from stresses which are applied thereto upon insertion in a printed circuit board or a cut-and-clinch operation.
