In a multilayer ceramic electronic component including directly plated external electrodes, in an exposed area defined by exposed portions of a plurality of internal conductors, an area ratio of the exposed portions in an end section of the exposed area is smaller than an area of exposed portions in a center section of the exposed area. Flux is thrown into the melt, and both the melt and the flux are brought into contact with each other sufficiently. In other cases, alternatingly n- and p-doped layers are then deposited. The button is mounted on the spring portion and covers the latch.
