Abstract: The present invention can suitably be used even in a site where hydrogen gas is metabolized slowly, such as the osseous tissue. Provided is a biodegradable implant including a biodegradable magnesium member formed of a magnesium alloy and coating layers that coat the biodegradable magnesium member, thereby reducing the degradation rate thereof in a living organism, wherein a depression to be infiltrated by an osteoblast is formed in a surface of the biodegradable magnesium member.
