    • PROBLEM TO BE SOLVED: To provide a seal-molding apparatus which can obtain a resin-sealed semiconductor package which is hard to cause wire flow even when fine-line wires are formed, and a manufacturing method for a resin-sealed semiconductor package using it.
      SOLUTION: The seal-molding apparatus having a mold clamping mechanism and a molding plunger advancing/retracting mechanism. The seal-molding apparatus has: a bottom mold 1 having a resin receiving part 7 for receiving a sealing resin formed at the upper part of the tip end face 3a in a bottom mold cavity section 4 in the state of the molding plunger 3 being retracted and loaded with a molding plunger 3 for compression molding movably back and forth so as to compress a sealing resin fed to the resin receiving part by the tip end face to constitute a bottom molding surface of the bottom mold cavity for molding in the state of the molding plunger 3 being advanced; a mold composed of this bottom mold 1 and a top mold 2 capable of being clamped by the mold clamping mechanism 6; and a resin feeder 20 which feeds an agitated-melted resin MR for sealing to the above resin receiving part 7 in the state of this mold being opened. The area of the tip end surface 3a of this molding plunger 3 is at least 90% to the area of the bottom molding surface of the bottom mold cavity.
