Abstract

A capacitor includes a body including a substrate having first and second capacitor regions, and first to third terminal electrodes disposed on an external surface of the body. The first capacitor region includes a plurality of first trenches, and a first capacitor layer disposed on one surface of the substrate and in the first trenches in the first capacitor region and including at least one first dielectric layer and first and second electrodes disposed with the at least one first dielectric layer interposed therebetween. The second capacitor region includes a plurality of second trenches, and a second capacitor layer disposed on one surface of the substrate and the second trenches in the second capacitor region and including at least one second dielectric layer and third and fourth electrodes disposed with the at least one second dielectric layer interposed therebetween. The second capacitor layer has a specific surface area greater than that of the first capacitor layer.
