1. A capacitor component comprising:
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,
wherein 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, and
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 side margin portion is M1, 0<A1<M1≤C1 and A1/C1≤0.60 are satisfied, and
when a porosity of the active portion is A2 and a porosity of the cover portion is C2, A2/C2≥0.003 is satisfied.
