To solve such a problem that an existing hip replacement arthroplasty is very invasive surgery that even a healthy bone except an affected site is scraped away in some cases because a standard product of an implant is mounted on a human body and then puts high burden on a doctor and the patient because a long time is needed to examine different optimum mounting locations of each patient and operate a bone scraping and the like.

A method of manufacturing an acetabular template of a circumference of an acetabular cup of a hip replacement arthroplasty comprises the step of obtaining a three-dimensional image data of a bone shape of a hip joint of each patient with CT, MRI, MRA and the like, the step of forming a shape data of the acetabular template including the acetabula by using the three-dimensional image data, the step of correcting the shape data of the acetabular template to a molding data for a three-dimensional laminating molding device, the step of forming a structure of the acetabular template with the three-dimensional laminating molding device based on the molding data, and the step of pouring an in-vivo activating material to a gap of the structure of the acetabular template.
