Abstract: Disclosed is a method for manufacturing a laminated piezoelectric composite. The method includes wet-mixing ceramic powder, a polymer binder, a plasticizer and a solvent for 4 to 72 hours so as to generate a mixed slurry, introducing the mixed slurry into a tape casting process so as to prepare a plurality of piezoelectric composite sheets, drying and forming the plurality of piezoelectric composite sheets using a roll-to-roll process so as to prepare the plurality of formed piezoelectric composite sheets, forming internal electrodes on the plurality of piezoelectric composite sheets so as to prepare the plurality of piezoelectric composite sheets having the internal electrodes, laminating and pressing the plurality of piezoelectric composite sheets having the internal electrodes so as to generate a piezoelectric composite sheet laminate having the internal electrodes, and cutting the piezoelectric composite sheet laminate having the internal electrodes into a desired shape and size.
