A thin-film common mode filter is provided, comprising: a pair of magnetic plates; upper/lower coil conductors formed between the magnetic plates, spirally wound in the magnetic plate surface direction, overlapped each other; upper/lower lead conductors one ends of which are connected electrically to one ends in centers of the upper/lower coil conductors, respectively, extended to external portions across these coil conductors; an upper/lower lead drawing terminals to which the other ends of the upper/lower lead conductors are connected, respectively; an upper/lower coil drawing terminals to which the other ends of the upper/lower coil conductors are connected, respectively; and each of the lower lead/coil drawing terminals and the upper coil/lead drawing terminals having a structure where at least two of conductor layers to be patterned into the upper/lower lead conductors and the upper/lower coil conductors are stacked, and brought into conduction with each other.
