Abstract: A multilayer capacitor includes a capacitor body having first to sixth surfaces, including a plurality of first and second dielectric layers and a plurality of internal electrodes stacked; and first and second external electrodes. The internal electrode includes first and second internal electrodes, a first floating electrode disposed between the first and second internal electrodes on the first dielectric layer, and second and third floating electrodes disposed on the second dielectric layer. The second floating electrode overlaps a portion of the first internal electrode and a portion of the first floating electrode, and the third floating electrode overlaps a portion of the second internal electrode and a portion of the first floating electrode. a/L is 0.113 or more, in which L is a length of the capacitor body, and a is a distance between the first floating electrode and the first or second internal electrodes.
