PROBLEM TO BE SOLVED: To provide a porous three-dimensional compression molded article which can respond to miniaturization of medical equipment and medical appliance and which can be enlarged in area after swelling.SOLUTION: In a porous three-dimensional compression molded article obtained by compression molding at least one porous body sheet, an area expansion ratio defined by a ratio S2/S1 of a total area S2 when the porous three-dimensional compression molded article is restored to a shape before compression relative to an apparent area S1 of the porous three-dimensional compression molded article is more than 5 times and less than 20 times.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2019,JPO&INPIT【課題】 医療機器や医療器具の小型化に対応しつつも、膨潤後には大面積化することが可能となる多孔質体立体的圧縮成形物を提供する。【解決手段】 少なくとも1枚の多孔質体シートが圧縮成形されてなる多孔質体立体的圧縮成形物であって、前記多孔質体立体的圧縮成形物の見かけ面積S1に対する、前記多孔質体立体的圧縮成形物が圧縮前の形状に復元した際の総面積S2の比S2/S1で定義される面積拡張比が、5倍を超えて20倍以下であることを特徴とする。【選択図】 図3
