An ultra high molecular weight polyethylene molded article for artificial joints has molecular orientation or crystal orientation in the molded article, and is low in friction and is superior in abrasion resistance, and therefore is available as components for artificial joints. Further, the ultra high molecular weight polyethylene molded article for artificial joints can be used as a component for artificial hip joints (artificial acetabular cup), a component for artificial knee joints (artificial tibial insert) and the socket for artificial elbow joints, and in addition to the medical use, it can be applied as materials for various industries by utilizing the characteristics such as low friction and superior abrasion resistance.

A prosthesis used for a damaged bone, an artificial articular cartilage or an artificial intervertebral disc being characterized in that the prosthesis is a composite body comprising polyvinyl alcohol hydrogel and ceramic or metallic porous body. With this prosthesis, PVA hydrogel enhances lubrication and shock absorbing functions, and the porous body allows the ingrowth and ossification of the bone tissue of a living body therein to affinitively connect said hydrogel to the bones of the living body.
