Two axis piezoelectric element

A piezoelectric element, comprising:

• a stack including a plurality of internal electrodes and a plurality of piezoelectric layers;
• and
• a surface electrode located on a side surface of the stack and electrically connected to the plurality of internal electrodes,
• wherein the plurality of internal electrodes includes
• a first electrode configured to bend the stack in a first direction perpendicular to a longitudinal direction of the stack by applying a voltage to the plurality of piezoelectric layers, and
• a second electrode configured to bend the stack in a second direction perpendicular to the longitudinal direction and the first direction by applying a voltage to the plurality of piezoelectric layers,
• at least one of the first electrode or the second electrode comprising:
• a first conductor comprising:
• a strip extending in the longitudinal direction;
• and
• an extension one end of which is connected to the strip, and another end of which is exposed at the side surface of the stack and connected to the surface electrode;
• and
• a second conductor between the extension and a portion opposite to an other portion where the another end of the extension is exposed,
• wherein the second conductor has a rectangular shape, and includes a round corner adjacent to the extension.
