Abstract: An optical reflection element includes a mirror portion and an oscillator coupled to the mirror portion. The oscillator includes a base, an insulating layer, a drive element, and a monitor element. The insulating layer is formed on the base. The drive element and the monitor element are formed on the insulating layer, and are separated from each other by a separation groove. Each of the drive element and the monitor element includes a lower electrode layer, a piezoelectric layer, and an upper electrode layer formed in that order on the insulating layer. The monitor element has high detection accuracy, allowing the optical reflection element to perform self-excited driving with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To provide a large turning angle of a mirror part 7 around a Y-axis.
SOLUTION: In an optical reflection element, the connection structure 13 of first oscillation parts 8A and 8B and the mirror part 7 is a cantilever structure in which the connection part of one first oscillation part 8A and a movable frame 9 is used as a fixed end 14. Thus the optical reflection element has higher freedom of the motions of the mirror part 7 and the first oscillation parts 8A and 8B, as a result, the large turning angle of the mirror part 7 around the Y-axis is available.
