To provide a superconductive wire with high Jc and provide a manufacturing method of the superconductive wire.

The manufacturing method includes a process to form a joined body by joining an oxide superconductive body or its precursor to a metal phase having 95% or higher orientation degree of a specified crystal plane and a process to adjust the c-axis orientation degree of the oxide superconductor body joined to the metal phase to be 95% or higher and the a- and b-axes conformity degree to be 75% or higher and by the method, the metal phase is made to be a polycrystalline body having 95% or higher orientation degree of a specified crystal plane and the crystal grains of the metal phase is made to have 2mm or longer length in the longitudinal direction, 4 or higher aspect ratio of the longitudinal direction to the width direction and the oxide superconductive body is made to have 95% or higher c-axis orientation degree and 75% or higher a- and b-axes conformation degree.
