Patent ID: 7417780

Claim:
A vibration mirror, configured to be reciprocatively vibrated by an electrostatic force to reflect an incident light beam such that a reflection direction of the reflected incident light beam is different from an incident direction of the incident light beam, comprising: a reflection means for reflecting the incident light beam; a reflection means holding substrate for holding the reflection means and comprising at least one resonant frequency adjustment plate for adjusting a resonant frequency of the vibration mirror, wherein the resonant frequency is adjusted by cutting the at least one resonant frequency adjustment plate; a first substrate comprising a torsional rotation shaft comprising rod members rotatably supporting two ends of the reflection means holding substrate; and a second substrate overlaid on the first substrate with an insulating layer therebetween so as to be electrically insulated from the first substrate, wherein the reflection means is formed on any one of surfaces of the first substrate and the insulating layer.
