Abstract
A capacitor array includes mutually opposed first and second internal electrodes having a first capacitance portion and a second capacitance portion, respectively, a first lead portion and a second lead portion, respectively, which are electrically connected to a first outer terminal electrode and a second outer terminal electrode, and a first protrusion portion and a second protrusion portion, respectively, which partially protrude toward the second outer terminal electrode and the first outer terminal electrode. The outer terminal electrodes have plating films directly connected to the internal electrodes. The plating film is formed by electrolytic plating. In the electrolytic plating, deposition of plating proceeds while being prevented from spreading in width directions of the individual side surfaces by electric fields generated from the protrusion portions toward the vicinities of exposure portions of the respective lead portions on the side surfaces.
