PROBLEM TO BE SOLVED : To provide a method for producing orientable ceramics which can be produced by using polycrystalline ceramic powder having a perovskite type structure and is reduced in restrictive conditions in terms of composition. SOLUTION : The method for producing the orientable ceramics includes a process for obtaining ceramic slurry containing the polycrystalline ceramic powder, a process for obtaining a ceramic molding by molding the ceramic slurry in a magnetic field, and a process for baking the ceramic molding. The polycrystalline ceramic powder contains a main component having the perovskite type structure and a subordinate component which is contained in a ratio of 5 mol or below (>0 mol) to 100 mol of the main component. The subordinate component is at least one selected from 3d transition metal ions the magnetic moments of which are not 0 or rare earth metal ions the magnetic moments of which are not zero.
