Abstract: A lens driving device includes: a fixed member; a lens-retaining member; a guide mechanism; a piezoelectric driving portion; and a pressing member. The lens-retaining member, the guide mechanism, the piezoelectric driving portion, and the pressing member are each configured as described in the specification. The pressing member is formed of a leaf spring member. The pressing member includes: a fixed portion to be fixed to the fixed member; a support portion configured to support the piezoelectric driving portion; and an elastically deformable portion that is provided between the fixed portion and the support portion and is elastically deformable. The support portion includes a plate-shaped base portion that is continuous with the elastically deformable portion, and a folded portion that is folded from the base portion in an L shape and projects toward the lens-retaining member. The piezoelectric driving portion is fixed to the folded portion.

Abstract: A module driving device includes a module holder configured to hold an optical module including a lens body and an imaging element; a connection member connected to the module holder such that the module holder is rockable about a first axial line that crosses a direction of an optical axis; a fixed-side member connected to the connection member such that the connection member is rockable about a second axial line that crosses the direction of the optical axis and is perpendicular to an axial line direction of the first axial line; and a driver including a plurality of shape memory alloy wires configured to move the module holder relative to the fixed-side member.
