## Abstract

A multilayered capacitor includes: a body that includes dielectric layers stacked in a first direction and a plurality of internal electrodes disposed to face each other with the dielectric layer interposed therebetween; and an external electrode that is disposed at the body and is connected to the internal electrode. Each of the plurality of internal electrodes includes a capacity portion disposed to overlap the internal electrode adjacent thereto and a drawing-out portion including a protruding portion extending from the capacity portion to be connected to the external electrode and protruding from one surface of the body in a second direction perpendicular to the first direction, the drawing-out portion includes a portion with a thickness greater than a thickness of the capacity portion in terms of a thickness along the first direction.

## Claims

### Claim 1

A multilayered capacitor comprising:
a body that includes dielectric layers stacked in a first direction and a plurality of internal electrodes disposed to face each other with one of the dielectric layers interposed therebetween; and
an external electrode that is disposed on the body and is connected to the internal electrode,
wherein each of the plurality of internal electrodes includes:
a capacity portion disposed to overlap an internal electrode adjacent thereto and
a drawing-out portion extending from the capacity portion to be connected to the external electrode and including a protruding portion protruding from one surface of the body in a second direction perpendicular to the first direction, and a portion having a thickness greater than a thickness of the capacity portion along the first direction, and
wherein a ratio of a length of the protruding portion along the second direction to the thickness of the capacity portion is within a range of 0.07 or more and less than 0.1.

### Claim 2 (depends on 1)
