Beschreibung
Zusammenfassung:	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.
