Abstract
The micromirror device includes a mirror part, a first actuator that reciprocally rotates the mirror part about the first axis, and a second actuator that reciprocally rotates the mirror part about the second axis. A resonance frequency Ain a lowest-order resonance mode as a resonance mode in which the mirror part and the first actuator are rotated about the first axis in opposite phases to each other, a resonance frequency B in a lowest-order resonance mode as a resonance mode in which the mirror part and the first actuator oscillate in opposite phases in a direction orthogonal to both of the first axis and the second axis, a frequency difference F=A−B, a resonance frequency C less than F and closest to the F, and a resonance frequency D greater than F and closest to F satisfy F−C≥20 Hz and F−D≤−150 Hz.
