Abstract: Disclosed herein is a multilayer capacitor that includes a capacitor layer having a plurality of odd-numbered electrode layers which are positioned at odd-numbered rows and a plurality of even-numbered electrode layers which are positioned at even-numbered rows. The capacitor layer includes a first side surface to which the odd-numbered electrode layers are exposed, a second side surface to which the even-numbered electrode layers are exposed, and a first planar region. The first external terminal covers the first side surface so as to be connected to the odd-numbered electrode layers. The second external terminal covers the second side surface so as to be connected to the even-numbered electrode layers. The first external terminal covers also the first planar region and is connected to the first internal electrode layer through a first via conductor extending in a stacking direction.
