To provide an actuator for light scanning which can adjust a movable range of a movable member and has flexibility of the movable range adjustment.

The actuator 10 for light scanning is equipped with: a fixing member 11 in which a light source 13 is installed; a movable member 14 which is loaded with an optical component 15 for refracting light emitted from the light source and which is rocked in the direction orthogonal to the optical axis of the optical component by a driving part 12; and a connecting member which connects between the fixing member and the movable member as well as supporting the movable member and which bends/deforms in the direction orthogonal to the optical axis of the light emitted from the light source with the rocking of the movable member. The actuator 10 scans, in the rocking direction, the light emitted from the light source by the rocking of the optical component incidental to the rocking of the movable member. The connecting member is composed of more than one pair of connecting members 17, 18, which are connected to each other through one or more deformation relaxing members 19 that relax the bend/deformation of the connecting members caused by the rocking of the movable member.
