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.
