PURPOSE:To provide a base material, with which foaming stock can be prevented from adhering to a cover mold and, at the same time, enough degassing is performed under the condition that the development of burr is suppressed, and the manufacturing method of a foam molded article by the use of the base material. CONSTITUTION:In a base material 10, which is arranged on one side of a skin 20 and has a foam molding space S formed against the skin 20, sealing surface 12, which comes in tight contact with the peripheral edge of the skin, is provided at the peripheral edge of the base material 10 and on which degassing grooves 14, which communicate the inside and outside of the foam molding space S with each other, are provided. Under the above-mentioned condition, the base material 10 is arranged to a cover mold, while the skin 20 is arranged to a cavity mold, so as to pour foaming stockin the foam molding space S made between the skin and the base material in order to expand the stock under the state that the inside and outside of the foam molding space S communicate with each other through the degassing grooves 14. |
