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 (1) including a biodegradable magnesium member (2) formed of a magnesium alloy and coating layers (3 and 4) that coat the biodegradable magnesium member (2), thereby reducing the degradation rate thereof in a living organism. Also provided is a biodegradable implant fabrication method including a coating step of coating a surface of a biodegradable magnesium member formed of a magnesium alloy with a coating layer that reduces the degradation rate in a living organism.
