<p>One embodiment of the present invention provides a piezoelectric device which includes a body part on which a plurality of piezoelectric layers are stacked, and an internal electrode which is arranged in the body part by interposing at least one piezoelectric layer among the piezoelectric layers and includes a material with a flake shape or a planar shape. An angle formed by a boundary surface between the internal electrode and the piezoelectric device by a contact of the internal electrode and the piezoelectric layer in the longitudinal direction of the material is 15 degrees or less.</p> |
