ABSTRACT:
An actuator includes: a base section; an object having a body portion and a holding portion holding the body portion in a manner that the body portion is movable against the base section; a movable comb-tooth portion extending from the object side in a direction substantially perpendicular to a formation direction of the holding portion; and a fixed comb-tooth portion which extends from the base section in a direction substantially perpendicular to the formation direction of the holding portion and which is arranged at a position at which the fixed comb-tooth portion is engaged with but having a gap from the movable comb-tooth portion; the fixed comb-tooth portion being composed of a steady-voltage-receiving fixed comb tooth that steadily supplies a drive voltage and a variable-voltage-receiving fixed comb tooth that receives a controlled voltage.
