Claim 0:
1. A multilayer ceramic capacitor comprising:
a body including a dielectric layer and first and second internal electrodes alternately disposed with the dielectric layer interposed therebetween, a first external electrode disposed on the body and connected to the first internal electrode, and a second external electrode disposed on the body and connected to the second internal electrode,
wherein the dielectric layer includes a first dielectric layer adjacent to the first internal electrode, a second dielectric layer adjacent to the second internal electrode, and a third dielectric layer disposed between the first dielectric layer and the second dielectric layer,
D1<D3 and D2<D3, in which D1 is an average particle size of dielectric grains included in the first dielectric layer, D2 is an average particle size of dielectric grains included in the second dielectric layer, and D3 is an average particle size of dielectric grains included in the third dielectric layer, and
a ratio of D3 to D1 (D3/D1) satisfies 1.3 to 2.3, and a ratio of D3 to D2 (D3/D2) satisfies 1.3 to 2.3.
