Abstract:
1. A mirror device comprising a mirror substrate having a mirror which is driven by a predetermined distance-dependent driving force and a support substrate which supports the mirror substrate, wherein the mirror substrate includes: at least one first mirror-side operating region on which the distance-dependent driving force acts, the first mirror-side operating region being integrally formed with the mirror and provided at a different position from the mirror; and at least one second mirror-side operating region on which the distance-dependent driving force acts, the second mirror-side operating region being provided at least one of one end of the mirror in a direction in which the mirror is driven and an opposite end of the mirror that is opposite the one end, wherein the support substrate includes: at least one first opposite-side operating section, the distance-dependent driving force acting between the first opposite-side operating section and the first mirror-side operating region; and at least one second opposite-side operating section, the distance-dependent driving force acting between the second opposite-side operating section and the second mirror-side operating region, wherein the first and second mirror-side operating regions and the first and second opposite-side operating sections are formed so that an attractive force is generated as at least part of the distance-dependent driving force, and wherein at least one of the mirror substrate and the support substrate is formed so that a gap between the first mirror-side operating region and the first opposite-side operating section is narrower than a gap between the second mirror-side operating region and the second opposite-side operating section.
