PURPOSE:To obtain Tc same as the bodies of the compacts by providing a form block in the gap between ceramic superconductive compacts, charging a slurry in which a ceramic superconductor is floating in those compacts and sinterring them to join in one body after dehydration. CONSTITUTION:A forming die is provided in the gap between ceramic superconductive compacts 1 and 1, slurry 3 in which ceramic superconductor is floating is charged in the compacts 1 and 1, and they are sintered to join in one body after dehydration. The slurry 3, thus, penetrates well into the fine gap at the end faces of the compacts 1 and 1, so that its adhesion to the compacts becomes preferable. And also, if a gypsum mold 2 is amployed as the forming die, density of powder increases due to suction force when moisture in the slurry 3 is absorbed into the mold 2, so that a sound sintered body can be obtained. Accordingly, Tc same as the bodies of compacts 1 and 1 can be obtained even on the joinning part.
