Zusammenfassung:	A lower mold (2) of a set of upper and lower molds for resin encapsulation of a lead frame having a semiconductor chip mounted thereon is provided with a tapered positioning pin (3) to be engaged with a positioning hole formed in the lead frame. A columnar portion of the tapered positioning pin has an outer diameter larger than an inner diameter of a positioning hole. An ejector pin (4) and an ejector pin in a pair (5) for ejecting a package out of the molds after the molding are fixed to an ejector pin coupling mechanism (6).
