Provided is a manufacturing method for preferentially-oriented oxide ceramics having a high degree of crystal orientation. The manufacturing method includes: obtaining slurry containing an oxide crystal B having magnetic anisotropy; applying a magnetic field to the oxide crystal B, and obtaining a compact of the oxide crystal B; and subjecting the compact to oxidation treatment to obtain preferentially-oriented oxide ceramics including a compact of an oxide crystal C having a crystal system that is different from a crystal system of one of a part and a whole of the oxide crystal B. By (1) reacting raw materials, (2) reducing the oxide crystal A, or (3) keeping the oxide crystal A at high temperature and quenching the oxide crystal A, the oxide crystal B is obtained to be used in the slurry.
