    摘要： A foamed resin article such as a seat pad, which enables the foamed resin article is released from a mold by sliding the foamed resin article along an inner surface of the mold, thereby significantly improving the workability of releasing from the mold and also provides a mold to be used in the method. The mold is provided with engaging projections 20, 30 and a pocket portion 40 formed in or on an inner surface of a core 3 thereof. A surface 10a of an embedment member 10 is positioned to face the core 3 and the surface 10a is superposed onto the surface of the core 3 such that the projections 20, 30 enter into large opening portions 12, 12. Then, the embedment member 10 is slid in such a manner as to introduce the projections 20, 30 into narrow portions 13 and wide portions 14, thereby retaining the embedment member 10 to the core 3. In this state, an end portion of the embedment member 10 is fitted into the pocket portion 40. To release the foamed resin article from the mold, the foamed resin article is slid in a direction opposite to the direction of the aforementioned sliding.
