A method of manufacturing a multilayered piezoelectric element having a multilayered structure by which an internal electrode and a side electrode are strongly connected. The method includes the steps of: forming first and second side surfaces by dicing the multilayered structure to protrude end portions of first and second electrode layers to an outer side than adjacent piezoelectric material layers and secure insulating regions between each electrode layer and respective one side surface; and forming a first side electrode on the first side surface and a second side electrode on the second side surface.
