The present invention is an artificial implant having an attachment portion for insertion into a patient's bone without attachment of bone cement or attachment to the patient's bone, which should be attached to the bone An outer surface of the attachment portion has a first layer formed of a synthetic resin material, and a second layer made of a metal material is fixed on the first layer, and the first base of the second layer is fixed. The end is porous or roughened to promote bone ingrowth or overgrowth, and the second distal end of the second layer is relative to the first proximal end There are few holes, almost no holes or almost roughened or smooth.
