1. A multilayer ceramic capacitor comprising:
a stacked body including:
a first main surface and a second main surface opposite to each other in a stacking direction;
a first lateral surface and a second lateral surface opposite to each other in a longitudinal direction orthogonal or substantially orthogonal to the stacking direction; and
a third lateral surface and a fourth lateral surface opposite to each other in a width direction orthogonal or substantially orthogonal to the stacking direction and the longitudinal direction; and
four external electrodes disposed on the stacked body; wherein
the four external electrodes include:
a first external electrode covering a portion of each of the first main surface, the first lateral surface and the third lateral surface;
a second external electrode covering a portion of each of the first main surface, the second lateral surface and the fourth lateral surface;
a third external electrode covering a portion of each of the first main surface, the first lateral surface and the fourth lateral surface; and
a fourth external electrode covering a portion of each of the first main surface, the second lateral surface and the third lateral surface;
about 0.85≤W/L≤about 1 is satisfied, where L denotes a dimension of the multilayer ceramic capacitor in the longitudinal direction, and W denotes a dimension of the multilayer ceramic capacitor in the width direction; and
a ratio of min [A1, A2, A3, A4] to max [A1, A2, A3, A4] is not less than about 36% and less than 100%, where A1, A2, A3, and A4 respectively denote surface areas of the first, second, third, and fourth external electrodes that are located on the first main surface of the stacked body.
