20 Claims

1. A capacitor component comprising:

a body including a dielectric layer and a plurality of internal electrode layers alternately disposed with each other, with the dielectric layer interposed therebetween; and

an external electrode disposed on the body and connected to the plurality of internal electrode layers,

wherein the dielectric layer has a central region, an upper region disposed above the central region and having a thickness of 10 or more to 30 nm or less in a direction from a boundary with the internal electrode layers to the central region, and a lower region disposed below the central region, and

wherein ionic mobility of the upper region of the dielectric layer is lower than ionic mobility of the central region of the dielectric layer.
