Disclosed is an acetabular cup implant for an artificial hip joint fitted to a bone using a shape memory alloy. The acetabular cup implant for an artificial hip joint comprises an acetabular cup for an artificial hip joint formed of a shape memory alloy having a semi-spherical shape with a hollow section and expanded upon arrival at a body temperature to be fitted to a bone, and a bearing installed in the hollow section of the acetabular cup to receive a femoral head to facilitate rotation of a femur. The acetabular cup implant for an artificial hip joint of the present invention can maximize fitting effect of an acetabular cup to a bone using expansion of a shape memory alloy constituting the acetabular cup for an artificial hip joint, and maximally prevent osteolysis due to intrusion of wear particles through a gap or relative movement between the acetabular cup and the bone and separation of the implant from the bone caused by expansive reproduction thereof, without addition of fixation using screws.
