1. A multilayer capacitor, comprising:
an active area, which contributes to formation of capacity of the multilayer capacitor, including first and second internal electrodes alternately stacked with a dielectric layer interposed therebetween, the active area having third and fourth surfaces opposing each other, and fifth and sixth surfaces connected to the third and fourth surfaces and opposing each other, the first internal electrode being in contact with the third, fifth, and sixth surfaces, the second internal electrode being in contact with the fourth, fifth, and sixth surfaces;
first and second side portions disposed on the fifth and sixth surfaces of the active area, respectively, to contact the first and second internal electrodes; and
first and second external electrodes disposed on the third and fourth surfaces of the active area, respectively, and connected to the first and second internal electrodes, respectively,
wherein one of the first and second side portions includes zirconium (Zr) and magnesium (Mg), and an Mg content of the one of the first and second side portions is 10 moles or more with respect to 100 moles of BaTiO3 (BT),
a Zr content of the one of the first and second side portions is equal to or less than 1 mole with respect to 100 moles of BaTiO3 (BT), and
the first side portion and the second side portion include a material different from the dielectric layer of the active area such that an interface is provided between the active area and the first side portion and the second side portion.
