PIEZOELECTRIC ELEMENT AND ELECTRONIC COMPONENT HAVING THE SAME

摘要

Disclosed is a piezoelectric element comprising: an element unit layer; an electrode layer including anode electrode layers and cathode electrode layers which are repetitively stacked in a vertical direction to cross each other on the element unit layer; a primary anode connection member to mutually connect the anode electrode layers; a primary cathode connection member to mutually connect the cathode electrode layers; at least one or more preliminary anode connection members which mutually connect the anode electrode layers and are arranged to be spaced apart from the primary anode connection member; and at least one or more preliminary cathode connection members which mutually connect the cathode electrode layers and are arranged to be spaced apart from the primary cathode connection member. The piezoelectric element further comprises: a primary electrode which is connected to the primary anode connection member and the primary cathode connection member and includes a pair of electrodes; and at least one or more preliminary electrodes which are arranged to be spaced apart from the primary electrode and include a pair of electrodes to be connected to the preliminary anode connection members and the preliminary cathode connection members.
