A resin composition that exhibits excellent moldability and excellent mechanical strength, and may suitably be used to produce a resin product that suppresses elution from the inner wall thereof is disclosed. In particular, a medical or biochemical resin composition that prevents adsorption of proteins, polypeptides, and peptides, and exhibits biocompatibility, antithrombogenicity, elution resistance, and moldability (e.g., injection moldability), and a resin molded product are disclosed. The medical or biochemical resin composition includes a polypropylene-based resin, and a hydrogenated derivative of a block copolymer shown by X-Y (wherein X represents s a polymer block immiscible with the polypropylene-based resin, and Y represents an elastomer polymer block of a conjugated diene), the polypropylene-based resin having a content of an antioxidant of 1 mass % or less and a content of an additive of 0.5 mass % or less, the additive being used to disperse the antioxidant in the polypropylene-based resin.
A medical or biochemical resin composition comprising a homopolypropylene resin, and a hydrogenated derivative of a block copolymer shown by X-Y,
