To provide a method and mold for molding a laminated molded object consisting of a resin core material and a skin and having a speaker grill not only to integrally mold the speaker grill simultaneously with molding but also to enhance the appearance capacity around the speaker grill while reducing manufacturing cost.

The skin 30 is set to the cavity formed between upper and lower molds 50 and 60, and the resin core material 20 and the skin 30 are molded at the same time by clamping the upper and lower molds 50 and 60 to mold the laminated molded object 10 and the speaker grill 11 is simultaneously molded by the punching pieces 52 and 63 of the upper and lower molds 50 and 60, and a groove part 53 is formed along the peripheral edge part of the punching piece 52 arranged to the upper mold 50. Whereupon, a molten resin M breaks through the skin 30 to be forcibly introduced into the groove parts 53 and extends to the product surface of the peripheral edge part of the speaker grill to enable the simultaneous molding of the speaker grill 11 in the laminated molded object.
