A method for manufacturing a semiconductor device including: fixing each of a plurality of semiconductor substrates onto a surface of a wiring substrate in which a perforation is formed in advance; covering the surface of the wiring substrate with a metal mold having a protrusion on an inner surface along the perforation; wholly sealing the plurality of semiconductor substrates with a sealing resin by introducing the sealing resin into the metal mold while forming a thin region in the sealing resin along the perforation; and dividing the wiring substrate into a plurality of chips by splitting the wiring substrate and the sealing resin along the perforation in the wiring substrate and the thin region in the sealing resin.
