PURPOSE:To provide a high temperature superconductor which can eliminate unevenness in the molding density likely generated inside of any superconductor, enlarge the critical current density, and increase the critical amperage value. CONSTITUTION:An oxide superconductive bulk material member or members 2 provided with large critical current density characteristics in advance by means of the middle pressurizing method due to uniaxial press are embedded in deep places beyond access of the pressurization made by a cold hydrostatic press, and after filling of superconductive powder, a molding process and pressure sintering process are applied as required, and thus a high temperature superconductor 1 is fabricated. |
