A method for fabricating a lamination structure of a second-generation high-temperature superconducting (2G-HTS) tape is provided. Suitable lamination tapes are selected and subjected to local oxidation on side to form a locally oxidized region having a target pattern. The lamination tapes and a to-be-laminated 2G-HTS tape are sequentially arranged, where the locally-oxidized side of each of the lamination tapes faces toward the 2G-HTS tape. The lamination tapes and the to-be-laminated 2G-HTS tape are simultaneously immersed in a molten solder pool, and subjected to reel-to-reel squeezing lamination to form the desired lamination structure. A lamination structure fabricated by the method is also provided.
