The socket has a configuration of a semi-spherical shell body, and the thickness thereof is thinner than that of a conventional artificial socket and the inner diameter thereof is substantially the same as that of a real socket in a human bone. An artificial hip joint using the artificial socket and a fixing screw suitable for the fixation of the socket in the pelvis are also disclosed.
