    Abstract: A multilayer capacitor includes a body including a laminate structure in which at least one first internal electrode and at least one second internal electrode are alternately stacked in a first direction with at least one dielectric layer therebetween, and first and second external electrodes spaced apart on the body, to be connected to at least one first internal electrode and at least one second internal electrode, respectively. The body includes, in a larger molar content, at least one selected from the group consisting of Dy, Tb, Y, Sm, Ho, Gd, Er, Ce, La and Nd in a capacitance formation region including a region between at least one first internal electrode and at least one second internal electrode than in a margin region including a region between a boundary line of at least one first internal electrode and at least one second internal electrode and a surface of the body.

    Abstract: An actuator may include a piezoelectric member extended to be elongated in an optical axis direction; and a magnetic body disposed on the piezoelectric member so as to decrease contact wear between the piezoelectric member and a lens barrel. According to exemplary embodiments of the present disclosure, driving reliability of the piezoelectric member maybe improved by decreasing contact wear due to the contact between the lens barrel and the piezoelectric member.
