PURPOSE:To prevent the opening of a bonding and to prevent the damage of a resin sealing layer by forming a connecting hand of narrow width at the connecting part of the bridge of a lead frame and the outer frame and forming a hole at the outer frame. CONSTITUTION:A connecting hand 11a of narrow width is formed at the connecting part of the bridge 15 of a lead frame body 10 made of an outer frame 11, a partition frame 12, an islant 13 a lead 14 and a bridge 15 with the outer frame 11, and a hole 16 is formed at the outer frame 11. In this manner, the opening of the bonding due to the displacement of the position of the lead can be prevented, the tensile strength applied to a resin layer at the time of curing and contracting the resin layer at the time of curing and conracting the resin sealing layer is alleviated, thereby preventing the damage at the resin sealing layer. |
