Abstract: A multilayer capacitor includes: a capacitor body including dielectric layers and first and second internal electrode layers and having first to sixth surfaces; and first and second external electrodes disposed on the third and fourth surfaces of the capacitor body, respectively. The first internal electrode layer is divided into a 1-1-th internal electrode connected to the first external electrode and a 1-2-th internal electrode by a first space portion disposed at a position close to the sixth surface, and the second internal electrode layer is divided into a 2-1-th internal electrode connected to the second external electrode and a 2-2-th internal electrode by a second space portion disposed at a position close to the fifth surface, such that the fifth and sixth surfaces of the capacitor body are in an electrically opened state.

Abstract: A multilayer capacitor includes a body including dielectric layers and internal electrodes and external electrodes disposed on an external surface of the body and connected to the internal electrodes. The body includes a first surface and a second surface to which the internal electrodes are exposed, the first surface and the second surface opposing each other in a first direction, a third surface and a fourth surface opposing each other in a second direction which is a direction in which the dielectric layers are stacked, and a fifth surface and a sixth surface opposing each other in a third direction. At least one of the internal electrodes include a first bottleneck structure having a first directional length of a third-directional outer region smaller than an inner region thereof and a second bottleneck structure having a third directional length of a first directional outer region smaller than an inner region thereof.
