Abstract:
1. A semiconductor device, comprising: a semiconductor chip having electrodes on the surface thereof, a plurality of lead terminal portions for electrical connection, a supporting portion on which the semiconductor chip is mounted, hanging lead portions each extending obliquely with respect to the lead terminal portions and supporting the supporting portion, metal wires for connecting the lead terminal portions and the electrodes of the semiconductor chip to each other, and a sealing resin for sealing the semiconductor chip and the metal wires in such a manner that a part of each lead terminal portion is exposed, wherein: lead terminal portions, among the plurality of the lead terminal portions, arranged adjacent to the hanging lead portions, each have a chamfered portion arranged at a head end thereof such that the chamfered portion extends substantially parallel with the hanging lead portion so as to avoid interference with the hanging lead portion, and the chamfered portion extends obliquely with respect to the lead portion having the chamfered portion.
