Abstract
Provided is a method for producing a porous material, wherein porosity can be controlled to 50% or higher by means of a freezing method, pore size can be controlled to 10 μm to 300 μm, and pore diameter distribution is uniform. The method is a method for producing a porous material, comprising freezing a mixture of water and a raw material comprising at least any of a ceramic material, a resin, a metal, and precursors thereof from a specific portion of the mixture to use ice crystals produced at the time as a pore source and then heat-treating a dry material obtained by removing the ice from the frozen material, wherein the mixture of a raw material and water or the frozen material comprises an antifreeze protein.
