PROBLEM TO BE SOLVED: To provide a microporous material of a three dimensional continuous network skeleton having micron and uniform pores, excellent in mechanical strength and, in addition, excellent in chemical properties such as solvent resistance and oil resistance. SOLUTION: Microporous materials can be obtained by subjecting an epoxy modified block copolymer composition to be obtained by mixing a composition comprising (A) 20-100 pts.wt. epoxy modified block copolymer obtained by epoxidizing a block copolymer composed of (A1) a polymer block mainly having a monomer unit based on a vinyl aromatic compound and (A2) a polymer block mainly having a monomer unit based on a conjugated diene compound, (B) 0-50 pts.wt. crosslinking agent having at least one functional group capable of reacting with epoxy groups, (C) 0.1-10 pts.wt. curing catalyst or curing accelerator which promotes the curing reaction of the epoxy modified block copolymer (A) alone or the epoxy modified block copolymer (A) with the crosslinking agent (B), and (D) 0-50 pts.wt. inorganic filler with (E) a low-molecular material to crosslinking reaction, and then removing the low-molecular material (E).
