摘要 Connection electrodes are formed to be located on the same plane as discrete internal electrodes, and to be exposed to the rear face while being insulated from the discrete internal electrodes. With the conductive relationship between the connection electrodes and common electrodes, the resistance of the common internal electrodes is reduced, and the size of the fixed area is also reduced accordingly.
