The invention relates to a multilayer isolation layer and an YBCO coating conductor formed on a metal basic belt, sequentially arranging an yttrium oxide film, an yttrium stabilized zirconium dioxide film, three lays of cerium dioxide film and a super-conductive layer YBCO layer on the cubic-structure metal basic belt. A manufacturing method for the multilayer isolating layer and YBCO coating conductor formed on the metal basic belt includes the following steps: (1) the metal basic belt is cleaned; (2) the metal basic belt is wrapped on to a belt-feeding wheel and a belt-collecting wheel; (3)metal-Y is adopted as a sputtering target and pre-sputtering is carried out; (4) the metal basic belt is delivered to a settlement zone to sputter and settle yttrium oxide; (5) metal-Zr-Y is adopted as the sputtering target and the pre-sputtering is carried out; (6) the metal basic belt passes through the settlement zone to sputter and settle the yttrium stabilized zirconium dioxide; (7) metal-Ceis adopted as sputtering target and the pre-sputtering is carried out; (8) the metal basic belt passes through the settlement zone to sputter and settle cerium dioxide; (9) a magnetron sputtering settlement of the YBCO coat is carried out; (10) the multilayer isolation layer and YBCO coat conductor formed on the metal basic belt is obtained. The method adopts steam to displace oxygen as reaction air, and the manufactured multilayer isolation layer has single cubic structure and the YBCO coat is formed on an extension part of the isolation layer. The forming of each film of the invention adopts a magnetron sputtering method so as to reduce manufacturing cost.
