The present invention provides a biocompatible material improved in biocompatibility owing to adsorption of a peptide that has high adhesion with a resin and hardly separates from a surface of the resin, and a functional material including the biocompatible material. The biocompatible material (10) includes a resin (1) and a peptide (2) adsorbed on the resin (1). The resin (1) has methoxycarbonyl groups and methyl groups, and tryptophan or arginine accounts for 70% or more of amino acid residues in the peptide (2) . As an alternative, the resin 1 is a fluorinated resin, and 2,3,4,5,6-pentafluoro-phenylalanine, 3-(trifluoromethyl)alanine, serine, threonine, histidine, aspartic acid, glutamic acid, phenylalanine, or aspartic acid accounts for 40% or more of the amino acid residues in the peptide (2). The functional material includes the biocompatible material (10), and a functional substance. The functional substance is held on a surface of the biocompatible material (10) or is released from the surface of the biocompatible material (10). |
