Abstract: Disclosed herein are a thin-type common mode filter and a manufacturing method thereof. According to an exemplary embodiment of the present invention, a thin-type common mode filter includes: a ferrite substrate having an upper surface on which irregular surface roughness is formed; an insulating layer formed on the upper surface of the ferrite substrate; and a conductive coil pattern formed in the insulating layer to be spaced apart from the upper surface of the ferrite substrate. Further, a manufacturing method of a thin-type common mode filter is proposed.
