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. The conductor layers include a pair of outermost conductor layers that are respectively nearest to the fifth and sixth surfaces, and thicknesses of the pair of outermost conductor layers are greater than a thickness of a center conductor layer nearest to a center of the capacitor element in a width direction.
