A three-terminal capacitor includes a capacitor element including first through sixth surfaces, first-side and second-side outer electrodes, a center outer electrode between the first-side and second-side outer electrodes, and conductor layers within the capacitor element. A height H2 is greater than a height H3, where the height H2 represents a higher one of a height at a center of a portion of the first-side outer electrode on the fifth surface and a height at a center of a portion of the first-side outer electrode on the sixth surface, and the height H3 represents a height at a center of a portion of the first-side outer electrode on the third surface, wherein the height H2 and the height H3 extend in the thickness direction.
