A lead frame is provided that prevents breaks in bonding wires caused by thermal stress which is applied when mounting a resin semiconductor. A plating layer is applied to the surfaces of internal leads to which bonding wires are to be connected and an insulating tape is adhered the internal lead 1 tips and bonding balls, so as to prevent peeling between the internal leads 1 and the resin, thereby preventing breaking of a bonding wire cause by stress applied during mounting. Additionally, a semiconductor device which makes use of this lead frame structure is provided.
