Abstract: Provided is an antibacterial biological implant capable of exhibiting superior antibacterial activity stably over a long period of time. The antibacterial biological implant 1 includes a substrate 2 made of a metal material and an anodized coating 3 provided on the substrate 2, the anodized coating 3 including an iodine-rich layer 31 located close to an interface S between the anodized coating 3 and the substrate 2.

Abstract: Provided is an antibacterial biological implant capable of exhibiting superior antibacterial activity stably over a long period of time. Also provided is a method for producing an antibacterial biological implant, the method including subjecting a substrate 2 successively to an anodization treatment, an acid treatment, and an iodine treatment to obtain an antibacterial biological implant 1.

Abstract: A method of producing metallic medical supplies includes supplying a metallic material selected from the group consisting of Ti, a Ti alloy, stainless steel and a Co—Cr alloy as a base material; treating the base material by carrying out anodic oxidation treatment in which an acid electrolytic bath or an alkali electrolytic bath is used as an electrolytic solution, and pulsed current having a frequency of 50 to 10,000 Hz is applied to the base material in the electrolytic solution to carry out electrolysis treatment to form a film having micro pores and/or micro unevennesses having a density of 5×104/mm2 or more on a surface of the base material; and carrying out iodine-impregnation treatment to impregnate the film with iodine or iodine compounds, wherein the metallic medical supplies have an antimicrobial activity value of not less than 2 to not more than 4.
