Abstract
A semiconductor element includes connection terminals. The connection terminals are each shaped in such a manner that the transverse cross-sectional area in a portion near the leading end thereof decreases toward the leading end. Specifically, the shape of each of the connection terminals is columnar except for the portion near the leading end, and the side surface in the portion near the leading end of the connection terminal is shaped in a tapered form. Furthermore, a metal layer for improving a solder wettability may be formed at least on the side surface shaped in the tapered form, of the connection terminal.
