Claim:
1. A multilayer ceramic electronic component comprising: a ceramic body including dielectric layers and satisfying T/W>1.0 when a width thereof is W and a thickness thereof is T; first and second external electrodes; and first and second internal electrodes alternately stacked to face each other, having the dielectric layer interposed therebetween, within the ceramic body, and electrically connected to the first and second external electrodes, respectively, wherein M1>M2, where M1 is a width in a width direction of the first and second internal electrodes stacked at an upper portion of the ceramic body in a thickness direction, wherein widths of the first and second internal electrodes stacked at the upper portion of the ceramic body are the same, and M2 is a width in a width direction of the first and second internal electrodes stacked at a lower portion of the ceramic body in the thickness direction, wherein widths of the first and second internal electrodes stacked at the lower portion of the ceramic body are the same, wherein an M2/M1 value is in a range in which acoustic noise is less than 20 dB and a relative capacitance decrease rate is less than 8% and greater than 1% with reference to a capacitance decrease rate of another multilayer ceramic electronic component in which M2/M1=0.99, and wherein a width in the width direction of the first acoustic noise decreasing part is constant in the thickness direction, a width in the width direction of the second acoustic noise decreasing part is constant in the thickness direction, a width in the width direction of the remaining portion of the first side margin part not including the first acoustic noise decreasing part is constant in the thickness direction, and a width in the width direction of the remaining portion of the second side margin part not including the second acoustic noise decreasing part is constant in the thickness direction.
