Abstract

Official abstract text for this publication.

A multilayer ceramic electronic component may include: a ceramic body in which dielectric layers containing plate-shaped dielectric grains are stacked; and internal electrodes disposed on the dielectric layers within the ceramic body. The dielectric layer may contain dielectric grains, plate-shaped surfaces of which have an angle of 20° or less with regard to a boundary surface between the dielectric layer and the internal electrode.

First claim

Opening claim text (preview).

What is claimed is: 1. A multilayer ceramic electronic component, comprising: a ceramic body in which dielectric layers containing plate-shaped dielectric grains are stacked; and internal electrodes disposed on the dielectric layers within the ceramic body, wherein the dielectric layer contains dielectric grains, plate-shaped surfaces of which have an angle of 20° or less with regard to a boundary surface between the dielectric layer and the internal electrode. 2. The multilayer ceramic electronic component of claim 1 , wherein when a diameter of the plate-shaped surface of the dielectric grain is a and a thickness of the dielectric grain is c, a/c≧1.5 is satisfied. 3. The multilayer ceramic electronic component of claim 1 , wherein when an area of the plate-shaped surface of the dielectric grain is s and a thickness of the dielectric grain is c, s/c≧2.25 is satisfied. 4. The multilayer ceramic electronic component of claim 1 , wherein the dielectric layer comprises a dielectric base material and bismuth. 5. The multilayer ceramic electronic component of claim 1 , wherein the dielectric layer comprises a dielectric base material, and the dielectric base material comprises a barium titanate-based dielectric material. 6. The multilayer ceramic electronic component of claim 1 , wherein the dielectric layer comprises a dielectric base material and bismuth, and the bismuth is contained in an amount of 0.2 to 1.6 moles based on 100 moles of the dielectric base material. 7. The multilayer ceramic electronic component of claim 1 , wherein the dielectric layer comprises a dielectric base material and bismuth, and the bismuth is contained as bismuthoxide (Bi 2 O 3 ) in an amount of 0.1 to 0.8 mole based on 100 moles of the dielectric base material. 8. The multilayer ceramic electronic component of claim 1 , wherein the dielectric grains, plate-shaped surfaces of which have an angle of 20° or less with regard to the boundary surface between the dielectric layer and the internal electrode, make up 60% or more of the dielectric grains contained in the dielectric layer.
