A multilayer capacitor includes a body including a dielectric layer and internal electrodes; and an external electrode disposed on the body to be connected to the internal electrode, wherein the dielectric layer includes a plurality of grains having a core-shell structure having a pore in a core, and the dielectric layer includes 20% to 40% of grains having two or less pores, among the plurality of grains.

Multilayer capacitor including dielectric layer with grains having pores

Disclosed herein is a multi-layered capacitor, including: an element formed by alternately multi-layering a dielectric layer and an internal electrode; and external terminals disposed at both ends of the element, wherein the dielectric layer disposed at an upper end U and a lower end L of the element is formed of a paraelectric material and the dielectric layer disposed at a central part C of the element is formed of a ferroelectric material.
