A laminate is prepared in which adjacent internal electrodes are electrically insulated from each other at an end surface at which the internal electrodes are exposed, a space between the adjacent internal electrodes, which is measured in the thickness direction of insulating layers, is about 10 μm or less, and a withdrawn distance of the adjacent internal electrodes from the end surface is about 1 μm or less. In an electroplating step, electroplating deposits deposited on the ends of the adjacent internal electrodes are grown so as to be connected to each other.
