To adjust the porosity of a porous liquid crystal polymer to a predetermined state.SOLUTION: A porous liquid crystal polymer 1 is prepared by extracting an inorganic salt 20 from a composition 2, in which the inorganic salt 20 is mixed with a liquid crystal polymer 10, into a solvent S at a predetermined temperature Tp. The solubility of the inorganic salt 20 in the solvent S at the predetermined temperature Tp is 10 g/100 ml or more.SELECTED DRAWING: Figure 1 【課題】多孔質液晶ポリマーの多孔性を所定の状態に調整する。【解決手段】多孔質液晶ポリマー１は、液晶ポリマー１０と無機塩２０とが混練された組成物２から所定温度Ｔｐを有する溶媒Ｓに無機塩２０を抽出させることによって製造される。所定温度Ｔｐの溶媒Ｓにおける無機塩２０の溶解度は、１０ｇ／１００ｍｌ以上である。【選択図】図１
