Abstract:
1. An optical scanning element comprising: a substrate; a first movable section supported on the substrate so as to be capable of rocking displacement about a first axis parallel to a surface of the substrate; a second movable section arranged integrally on the first movable section and supported so as to be capable of rocking displacement about a second axis perpendicular to the first axis, the second movable section having a micro mirror on an upper surface thereof; and a driving section that applies a physical action force on the first movable section and the second movable section so as to cause the micro mirror to perform rocking displacement in two axial directions about the first axis and the second axis, wherein the driving section includes: a first driving section that applies a physical action force on the first movable section in a first rotational direction about the first axis; a second driving section that applies a physical action force on the first movable section in a second rotational direction opposite to the first rotational direction, the first and second driving sections being arranged within a region overlapping with the first movable section in a first thickness direction thereof when being viewed in the first thickness direction; a third driving section that applies a physical action force on the second movable section in a third rotational direction about the second axis; and a fourth driving section that applies a physical action force on the second movable section in a fourth rotational direction opposite to the third rotational direction, wherein the third driving section and the fourth driving section are arranged at a height position between the first movable section and the second movable section.
