The present invention relates to a manufacturing method and thus by artificial disc of the artificial disc, and a first upper plate member formed with a plurality of spikes on the upper surface, is formed insert injection to the first upper plate member, the a first upper plate member and when formed from a material of the hetero ( ) top plate made of a second top plate member concave groove is formed in the convex portion is formed on an upper side to be coupled to the concave groove of the upper panel, the upper panel is convex the It is formed so as to flow along the lower end edge is formed in zipper, and the intermediate is formed of the same material as the second upper member, and the first lower plate members a plurality of keel is formed on a lower, insert injection to the first lower plate member It formed and the first lower plate member and the material of the hetero ( ), and the intermediate is formed of the same material, the coupler of the intermediate body, including a lower plate made of a second lower plate member having a coupling groove to engage receiving a second top plate cutting operation after re-insert injection molding to form a top plate, forming the first to the plate, the second and the plate to the insert injection molding to form the artificial disc and the first upper plate member, characterized in and that made forming a lower plate by a cutting process after, and a method for manufacturing an artificial disc characterized in that for molding the intermediate to a technical base. Thus, by forming an upper plate and a lower plate which contacts the mating surface of the intermediate of the same material as the intermediate improve the durability of the artificial disc and, by improving the structure of the artificial disc to mitigate the impact even like the human body movement, or, an electronic there is an advantage.본 발명은 인공 디스크의 제조방법 및 이에 의한 인공 디스크에 관한 것으로서, 상면에 복수개의 스파이크가 형성된 제1상판부재와, 상기 제1상판부재에 인서트사출형성되며, 상기 제1상판부재와는 이종(異種)의 재질로
