Abstract
An antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration is provided. The antibacterial member includes a DLC film (F-DLC film)containing fluorine at least partially or entirely on an outermost surface of a base material. The F-DLC film has an element ratio (F/(F+C)) of 17% to 72% and a nanoindentation hardness of 2,000 MPa to 16,000 MPa. This maintains wear resistance and close contact, and obtains an antibacterial member that maintains a high antibacterial property and a high osteoconductive property for a long duration. The F-DLC film does not necessarily need to cover the entire outermost surface of the base material but may be disposed in a mottled pattern.
