Abstract
A titanium member includes a first region where a plurality of first convex structural bodies extending in a first direction are arranged on the surface of the titanium member in a second direction orthogonal to the first direction, the first convex structural body has first convex portions arranged on an upper surface of the first convex structural body at an interval of several hundred nanometers along the first direction, and a height of the first convex portion is several ten nanometers. It is preferable that the first convex structural bodies adjacent in the second direction are arranged at an interval wider than the interval at which the first convex portions are arranged, and in the first convex structural bodies, a height including the first convex portion is higher than the height of the first convex portion.
