Abstract: A ceramic electronic component includes two electronic-component main bodies and two metal terminals. Each of the metal terminals includes a base, ribs on left and right sides of the base, and a mounting portion below the base. The base includes two bonding portions to be bonded to respective external electrodes of the two electronic-component main bodies and cut-out portions each having a closed shape and being disposed below the respective bonding portions.
