PURPOSE:To provide a porous organic semiconductor having excellent heat- resistance and oxidation resistance, consisting of a heat-treated product of a specific aromatic condensation polymer having a polyacene skeleton structure with a specific C/H atomic ratio and containing minute interconnected pores. CONSTITUTION:An aromatic condensation polymer obtained by the condensation of an aromatic hydrocarbon compound having phenolic hydroxyl group and an aldehyde is heat-treated to obtain a porous semiconductor having a polyacene skeleton structure with a C/H atomic ratio of 0.6-0.05 and containing interconnected pores having average diameter of <=10mum. It can be produced by pouring an aqueous solution containing a precondensate and an inorganic salt into a mold, heating the solution while suppressing the evaporation of water to obtain a hardened product having the form of a film or cylinder, removing the inorganic salt therefrom, and heat-treating the resultant porous cured condensate in a nonoxidizing atmosphere at 400-800 deg.C.
