The suppression of resin leakage is combined with the suppression of damage to the functional wiring area of a wiring board in forming an encapsulation resin. A method for manufacturing a semiconductor device includes the step of clamping a wiring board with a first mold and a second mold. The second mold includes: a flat portion contacting a wiring board; a recessed portion forming a cavity to form an encapsulation resin; and a projecting portion formed at a location spaced apart from the recessed portion on the flat portion, the projecting portion projecting on the first mold side, and extending along the first edge of the wiring board. |
