PROBLEM TO BE SOLVED: To stably impart an antithrombic function to a medical base material over a long period by fixing a compound containing a plurality of amidino groups or guanidino groups in a molecule as well as the prescribed number of aromatic rings to a base material surface by chemical bonding. SOLUTION: A compound containing a plurality of amidino group or guanidino groups and one or more aromatic rings in a molecule is fixed to a base material surface by chemical bonding to form a medical base material. The compound may have a structure expressed by the formula, where R1 to R5 stand for hydrogen, a halogen atom or an alkyl group, and n stands for an integer of 0 or 1. Also, tris(4-amidinophenyl)1,3,5-benzenetricarboxylate trihydrochloride or the like may be used as the compound. |
