Disclosed herein is a common mode filter including an internal electrode manufactured in a coil electrode form and provided with a simultaneous coil pattern in which two coil electrodes are overlapped with each other in a single layer in a direction in which a coil is wound, wherein a height of a second insulating layer formed on the internal electrode is higher than an interval between the coils. Therefore, a portion at which a parasitic capacitance is generated may be basically blocked, and a self resonant frequency (SRF) may be increased while filtering performance as the common mode filter is maintained.
