Claim 11:
12. A multilayer capacitor comprising:
a body including a stack 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 interposed therebetween thereby defining a capacitance formation region; and
first and second external electrodes spaced apart from each other and disposed on the body to be respectively connected to the at least one first internal electrode and the at least one second internal electrode,
wherein each of the first and second external electrodes includes:
a first conductive layer including a first conductive material;
a second conductive layer including a second conductive material having a standard reduction potential, higher than a standard reduction potential of the first conductive material, and contacting a portion of an external surface of the first conductive layer; and
an oxide layer disposed between another portion of the external surface of the first conductive layer, overlapping the body in the first direction, and the second conductive layer, and including an oxide of the first conductive material, and
wherein the oxide layer is disposed on a portion of an area of the body, other than respective portions of both surfaces of the body which overlap the capacitance formation region in a direction in which the first and second external electrodes face each other.
