PROBLEM TO BE SOLVED : To provide a method for manufacturing a tape-like RE-based oxide superconducting wire material having excellent superconducting characteristics with a desired thin thickness.SOLUTION : The method for manufacturing a tape-like RE-based oxide superconducting wire material includes : a coating step of applying a superconducting raw material solution on an intermediate layer formed on a substrate; a calcination heat treatment step of calcinating the applied solution to form a calcined film; and main firing heat treatment step of laminating a calcined film by repeating the coating step and the calcination heat treatment step so as to form a superconducting layer precursor and applying a main firing heat treatment to the precursor so as to form a superconducting layer. The superconducting layer is formed of REBaCuO(RE represents at least one element selected from Y, Nd, Sm, Eu, Gd, and Ho). In the calcination heat treatment step, a batch-type electric furnace is used to make the calcined film.
