PURPOSE:To obtain a cell-culture substrate having excellent adhesivity, distensi bility and proliferativity of cell and enabling cell culture over a long period in high density, by supporting sugars or proteins, etc., on a surface of a compos ite of a polymeric material and an inorganic material. CONSTITUTION:A composite of a polymeric material and an inorganic material is produced by filling or laminating an inorganic material such as alumina, silicon dioxide, hydroxyapatite, etc., to a polymeric material composed of a polymer such as olefinic polymer, polyester resin, etc., and formed preferably in the form of porous material, tube, hollow fiber, etc. One or more components selected from sugars, proteins, lipids and their composite compounds are supported on the whole surface of said composite material or partially on the surface e.g. in the pattern of lattice, stripes, dots, etc.
