In a laminated piezoelectric body, a laminated piezoelectric body manufacturing method, an ultrasound transducer, and an ultrasound diagnostic device according to the present invention, a plurality of mutually laminated piezoelectric bodies are electrically connected in parallel to each other, and each of the plurality of piezoelectric bodies arranges an orientation of residual polarization or a crystal axis that is related to an electrical displacement or a sign of an electric field due to a direct piezoelectric effect in a direction which reduces sensitivity in a first resonance mode and increases sensitivity in a second resonance mode of a higher order than the first resonance mode with respect to an axis of a first-level piezoelectric body on a fixed end-side.
