Abstract
A multilayer capacitor that achieves reduced acoustic noise includes a capacitor body including a capacitance generating portion, a first outer layer portion, and a second outer layer portion. First and second internal electrodes are provided in the capacitance generating portion. The first outer layer portion is located between the capacitance generating portion and a first principle surface. The second outer layer portion is located between the capacitance generating portion and a second principle surface. The second outer layer portion is thicker than the first outer layer portion. At least one of a concave portion and a convex portion is provided on the second principle surface.
