Abstract
To provide a porous molding that can be used as a molding that has sufficient strength to be self-supportable even when the dimensions change due to absorbing water and that can be suitably used as a filter for removing impurities in a liquid or gas. A porous molding is achieved by sintering a mixed powder including a dried gel powder and a thermoplastic resin powder, wherein the ratio of average particle diameter dof the thermoplastic resin powder to the average particle diameter dof the dried gel powder d/dis 1.3 or greater, and the difference ratio of average particle diameter dof the thermoplastic resin powder to the average particle diameter dof the dried gel powder and the average particle diameter dof the dried gel powder when absorbing water and swelling is (d−d)/dis 4.0 or less.
