1. A multilayer capacitor comprising:
a body including a dielectric layer and a plurality of internal electrodes stacked on one another with the dielectric layer interposed therebetween; and
external electrodes disposed externally on the body, and respectively connected to the plurality of internal electrodes,
wherein at least one of the plurality of internal electrodes includes an alloy region formed in a region in contact with a corresponding external electrode of the external electrodes, and the alloy region includes a nickel (Ni)-chromium (Cr) alloy, and
a region of the at least one of the plurality of internal electrodes other than the alloy region has a lower content of Cr than the alloy region.
