Claim:
1. A laminated chip electronic component for mounting on a printed circuit board (PCB) via solder, the solder contacting the laminated chip electronic component and the PCB, the laminated chip electronic component comprising: (i) a ceramic body including: an active region, in which a plurality of internal electrodes are alternately disposed in a mutually opposing manner and dielectric layers are interposed between the internal electrodes to form capacitance; an upper cover layer on an upper surface of an uppermost internal electrode of the active region; and a lower cover layer on a lower surface of a lowermost internal electrode of the active region and having a thickness greater than that of the upper cover layer and being adjacent to the printed circuit board; and (ii) first and second external electrodes on the ceramic body, wherein the plurality of internal electrodes are alternately connected to the first and second external electrodes respectively, and such that a center of the active region in a thickness direction is above a center of the ceramic body in the thickness direction; and wherein a point of maximum deflection at each side of the ceramic body in a length direction when an external voltage is applied to the active region is at or above a level of a height of the solder in the thickness direction, and when half of a thickness of the ceramic body is defined as A, a thickness of the lower cover layer is defined as B, half of a thickness of the active region is defined as C, and a thickness of the upper cover layer is defined as D, (2×C)>A and 0.021≦D/B≦0.422.
