Abstract: The preset invention has as its object the provision of a laminate free of hexavalent chromium and excellent in corrosion resistance and wear resistance, and a manufacturing process of the laminate. To solve the above-described problems, a laminate according to the present invention includes a substrate, and a laminated film portion with metal films laminated in two or more layers. The laminate has an interface layer between each two adjacent ones of the metal films. The laminated film portion contains a first metal element as a principal component, the first metal element being at least one element of Ni, Cr, Co, and W, and a second metal element that is a metal element of smaller cohesive energy than that of the first metal element. The second metal element contained in the interface layer is at a content ratio higher than that of the second metal element contained in each of the adjacent metal films.

Abstract: 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 includes a resin and a peptide adsorbed on the resin. The resin has methoxycarbonyl groups and methyl groups, and tryptophan or arginine accounts for 70% or more of amino acid residues in the peptide. As an alternative, the resin 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. The functional material includes the biocompatible material, and a functional substance. The functional substance is held on a surface of the biocompatible material or is released from the surface of the biocompatible material.
