Abstract
A micromirror device includes a first support portion that is connected to the mirror portion on a first axis located in a plane including the reflecting surface of the mirror portion in a stationary state, and that swingably supports the mirror portion around the first axis. The first support portion is composed of a main shaft stretched along the first axis and a plurality of sub-shafts symmetrically disposed on both sides of the main shaft across the first axis and stretched along the first axis, the first support portion has a folded structure having three or more folded portions formed by connecting the plurality of sub-shafts, and in a case where inner curvature radii of the folded portions are denoted by R, R, R, . . . , in order from the closest to the first axis, a relationship of 0.73≤R/R≤0.9 (k=1, 2, . . . ) is satisfied.
