Abstract:
1. A multilayer capacitor comprising: an element body formed by laminating a plurality of dielectric layers, the element body having a pair of end surfaces and four lateral surfaces connecting the end surfaces; a first terminal electrode covering one end side of the element body; a second terminal electrode covering an other end side of the element body; a first internal electrode formed inside the element body so as to extend between the one end side of the element body and the other end side of the element body, and electrically connected to the first terminal electrode; and a second internal electrode formed inside the element body so as to extend between the one end side of the element body and the other end side of the element body with a dielectric layer sandwiched between the second internal electrode and first internal electrode, and electrically connected to the second terminal electrode, wherein the first terminal electrode has a first end portion covering the end surface at the one end side of the element body and first lateral portions covering the one end side of the element body at the four lateral surfaces, the second terminal electrode has a second end portion covering the end surface at the other end side of the element body and second lateral portions covering the other end side of the element body at the four lateral surfaces, the first internal electrode has a first principal-surface electrode portion and a second principal-surface electrode portion in order from the other end side of the element body toward the one end side of the element body, and a first lead portion respectively connecting the second principal-surface electrode portion and the first lateral portion of the first terminal electrode, the second internal electrode has a fourth principal-surface electrode portion and a fifth principal-surface electrode portion in order from the one end side of the element body toward the other end side of the element body, and a second lead portion respectively connecting the fifth principal-surface electrode portion and the second lateral portion of the second terminal electrode, in a width direction of the first internal electrode and the second internal electrode, the second principal-surface electrode portion is greater than the first principal-surface electrode portion, and the fifth principal-surface electrode portion is greater than the fourth principal-surface electrode portion, when viewed from a lamination direction of the element body, an outer edge of the second principal-surface electrode portion at the other end side of the element body is arranged near the other end side more than an outer edge of the fifth principal-surface electrode portion at the one end side of the element body, or arranged so as to be aligned with the outer edge of the fifth principal-surface electrode portion at the one end side of the element body, the first internal electrode has a third principal-surface electrode portion at the one end side of the element body in the second principal-surface electrode portion, the second internal electrode has a sixth principal-surface electrode portion at the other end side of the element body in the fifth principal-surface electrode portion, in the width direction, the third principal-surface electrode portion is smaller than the second principal-surface electrode portion, and the sixth principal-surface electrode portion is smaller than the fifth principal-surface electrode portion, outer edges of the first principal-surface electrode portion are separate from the lateral surfaces and extend straight along a longitudinal direction from the outer edge of the second principal-surface electrode portion at the other end side of the element body, outer edges of the fourth principal-surface electrode portion are separated from the lateral surfaces and extend straight along a longitudinal direction from the outer edge of the fifth principal-surface electrode portion at the one side of the element body, an outer edge of the first lead portion at the one end side of the element body is aligned with the outer edge of the second principal-surface electrode portion at the one end side of the element body, an outer edge of the second lead portion at the other end side of the element body is aligned with the outer edge of the fifth principal-surface electrode portion at the other end side of the element body, and in a longitudinal direction of the first internal electrode and the second internal electrode, the outer edge of the second principal-surface electrode portion at the other end side of the element body extends to the second lead portion, and the outer edge of the fifth principal-surface electrode portion at the one end side of the element body extends to the first lead portion.
