Piezoelectric device

A piezoelectric device comprising:

• a first piezoelectric layer with a thickness in a first direction, and including an upper surface being one surface of the first piezoelectric layer in the first direction, and a lower surface being another surface of the first piezoelectric layer in the first direction;
• a first support on a lower surface side of the first piezoelectric layer;
• a first upper electrode on the upper surface of the first piezoelectric layer;
• a first lower electrode on the lower surface of the first piezoelectric layer, and at least partially facing the first upper electrode;
• a second piezoelectric layer including an upper surface being one surface of the second piezoelectric layer in the first direction, and a lower surface being another surface of the second piezoelectric layer in the first direction;
• a second support on a lower surface side of the second piezoelectric layer;
• a second upper electrode on the upper surface of the second piezoelectric layer;
• a second lower electrode on the lower surface of the second piezoelectric layer, and at least partially facing the second upper electrode;
• and
• an intermediate layer;
• wherein
• the upper surface of the first piezoelectric layer and the upper surface of the second piezoelectric layer face each other in the first direction;
• and
• the intermediate layer is located between the upper surface of the first piezoelectric layer and the upper surface of the second piezoelectric layer.
