Abstract
A novel method for producing an olefinic resin porous material is provided. The method for producing an olefinic resin porous material disclosed herein includes the steps of preparing a single phase in which an olefinic resin and a solvent are mixed each other, in a pressure-resistant container, introducing high pressure carbon dioxide into the pressure-resistant container, and releasing the pressure in the pressure-resistant container. In this method, introducing the high pressure carbon dioxide is carried out such that the pressure in the pressure-resistant container reaches 6 MPa or higher.
