ABSTRACT:
A biodegradable plastic of a screw-fastened portion which remains on a metal component can be decomposed and dissolved by immersing in a degradative enzyme while being joined with the metal component. Further, since the amount of the biodegradable plastic is small and a shape such as a groove is provided which can increase a contact area with the degradative enzyme, decomposition can be completed in a short time.
