Both ends of the lead arrangement project outward from side surfaces of a package to form outer lead regions. Each of the outer lead regions includes a pair of outer lead projections and lead terminal smaller projections that are located between the outer lead projections. The outer lead projections and lead terminal smaller projections project outward. Adjustment is made to the projection amount of end surfaces of the lead smaller projections lying in a plane perpendicular to a longitudinal direction of the lead arrangement, whereby the end surfaces projecting less than end surfaces of the outer lead projections. Thus, cut surfaces of lead connection portions with edged corners are not exposed. This arrangement prevents that the cut surfaces damage other devices.
