Claim 7:
8. A multilayer capacitor, comprising:
a capacitor body including dielectric layers, first internal electrodes and second internal electrodes, and having first and second surfaces opposing each other, third and fourth surfaces connected to the first and second surfaces and opposing each other, fifth and sixth surfaces connected to the first and second surfaces and to the third and fourth surfaces and opposing each other, wherein the first internal electrodes are exposed through the third surface, and the second internal electrodes are exposed through the fourth surface; and
first and second external electrodes disposed on the third and fourth surfaces, respectively, and connected to the first and second internal electrodes, respectively,
wherein the capacitor body further includes an active region in which the first and second internal electrodes are alternately disposed with the dielectric layers interposed therebetween, and upper and lower cover regions disposed on the upper and lower surfaces, respectively, in a stacking direction of the active region,
wherein width margins of the capacitor body are disposed on opposite sides of the active region in a direction connecting the fifth surface and the sixth surface to each other, each width margin includes a first region disposed on an internal side thereof and a second region disposed on an external side thereof, and the upper and lower cover regions each include a third region disposed on an internal side thereof and a fourth region disposed on an external side thereof,
wherein the second region and the fourth region have a dielectric constant A, and the first region and the third region have a dielectric constant B, and
wherein A and B are different and satisfy 0.5≤B/A.
