An SMD(Surface Mount Device) type EMI(ElectroMagnetic Interference) filter is provided to decrease a size of an electronic apparatus by integrating at least two capacitors with different capacitances into a single semiconductor chip. An SMD type EMI filter includes a first functional ceramic(100), first inner electrodes(110,120), a second functional ceramic(200), and second inner electrodes(210,220). The first inner electrodes are laminated on the first functional ceramic and configured to be extracted to one end widthwise. The second functional ceramic is laminated to cover the first inner electrodes. The second inner electrodes are formed on the second functional ceramic and extracted to both ends lengthwise. Overlap areas of the respective second inner electrodes on the first inner electrodes are different from each other. |
