摘要：
The present invention addresses a problem of providing a three-dimensional structure having bioactivity in which a coating film includes a titanium alkoxide hydrolysis product is coated with high adhesion strength on the surface of a three-dimensional structure main body having a concave section and/or a convex section on the surface, and also providing a method for producing such three-dimensional structure. The three-dimensional structure having bioactivity of the present invention includes a three-dimensional structure main body made of a polymer and having a concave section and/or a convex section on a surface, and having a coating film on the surface of the three-dimensional structure main body, and the coating film that includes a titanium alkoxide hydrolysis product, and the coating film has a thickness of 10 nm to 200 nm. No cracks or peelings of the coating film can be recognized when the concave section and/or the convex section on the surface of the three-dimensional structure is observed with a scanning electron microscope at a magnification of 300, and the coating film has bioactivity when evaluated under conditions specified in ISO 23317.
