| description | The invention provides a process for producing a porous body having desired regions different in physical properties not by bonding two or more porous members with an adhesive or the like but by pore-forming treatment. The process comprises preparing at least two kinds of raw materials which each comprises both a polymer and a solvent for the preparation of raw material and which are different incomposition, freezing each raw material into a desired shape, bringing the obtained frozen bodies into contact with each other to form an assembly of the frozen bodies, exposing the assembly to such conditions that the frozen bodies begin to melt, and then freeze-drying the resulting assembly. Thus, a porous body having regions different in physical properties can be obtained and the body is useful as an adhesion inhibitor or an anchorage material for cell culture or the like. |
