Abstract:
Disclosed herein is a multilayer ceramic device including: a device body having side surfaces spaced apart from each other and circumferential surfaces connecting the side surfaces to each other; internal electrodes disposed in a length direction of the device body in the device body; external electrodes having a front surface portion covering the side surfaces and a band portion extended from the front surface portion and covering portions of the circumferential surfaces; and crack guide patterns disposed in the device body and guiding a progress direction of a crack generated from the circumferential surfaces so that the crack is directed toward the side surface, wherein the crack guide pattern includes: a first metal pattern; and a second metal pattern disposed to be closer to the circumferential surface as compared with the first metal pattern and having gaps.
