摘要： Disclosed is a multilayer capacitor capable of improving reliability and further reducing ESL. In a width direction, a second principal-surface electrode portion is greater than a first principal-surface electrode portion, and a fifth principal-surface electrode portion is greater than a fourth principal-surface electrode portion. When viewed from a lamination direction, an outer edge of the second principal-surface electrode portion at the other end side is arranged near the other end side more than outer edge of the fifth principal-surface electrode portion at one end side. First lead portions are connected to the second principal-surface electrode portion, and second lead portions are connected to the fifth principal-surface electrode portion. Thus, portions of the second principal-surface electrode portion greater than the first principal-surface electrode portion and portions of the fifth principal-surface electrode portion greater than the fourth principal-surface electrode portion function as current paths between the first lead portions and the second lead portions. Therefore, the current paths are shortened.
