    摘要： A multilayer capacitor includes a capacitor body including an active region having dielectric layers and internal electrodes alternately stacked therein, the capacitor body including upper and lower covers disposed on upper and lower surfaces of the active region, respectively; and an external electrode disposed on an external surface of the capacitor body. In one of the upper and lower covers, a portion thereof between a boundary surface of the active region and a boundary surface of the capacitor body is divided into a first cover region adjacent to the active region and a second cover region adjacent to the boundary surface of the capacitor body, and the first cover region includes grains having a core-shell structure doped with Sn. The first cover region includes 20% or more of Sn-doped core-shell structure grains, compared to the total of grains in the first cover region.

    摘要： A multilayer capacitor includes a body including a laminate structure in which at least one first internal electrode and at least one second internal electrode are alternately stacked in a first direction with at least one dielectric layer therebetween, and first and second external electrodes spaced apart on the body, to be connected to at least one first internal electrode and at least one second internal electrode, respectively. The body includes, in a larger molar content, at least one selected from the group consisting of Dy, Tb, Y, Sm, Ho, Gd, Er, Ce, La and Nd in a capacitance formation region including a region between at least one first internal electrode and at least one second internal electrode than in a margin region including a region between a boundary line of at least one first internal electrode and at least one second internal electrode and a surface of the body.
