PURPOSE: A manufacturing method of a high temperature superconductor Lu-123 is provided to easily control the amount of purities by using a polymeric precursor synthesizing method. CONSTITUTION: A raw material is mixed with barium compound and copper oxide. The mixed raw material is pulverized into fine powder (S10). The fine powder is calcinations processed (S20) in an atmospheric annealing gas atmosphere. The fine powder sintering processed in an atmospheric sintering gas atmosphere (S40). A sintering body is collected (S50).
