  • Publication number: 20240145171
    Abstract: A capacitor component includes a body including a dielectric layer and first and second internal electrode layers, and external electrodes disposed on the body and connected to the first and second internal electrode layers, respectively. The body includes an active portion in which the first and second internal electrode layers are alternately disposed with the dielectric layer interposed therebetween, a cover portion disposed on an upper portion and a lower portion of the active portion, and a side margin portion disposed on both sides of the active portion opposing each other. When a content of magnesium (Mg) included in the active portion is A1, a content of magnesium (Mg) included in the cover portion is C1, and a content of magnesium (Mg) included in the margin portion is M1, 0<A1<M1?C1 and A1/C1?0.60 are satisfied.
