PROBLEM TO BE SOLVED: To provide a common mode noise filter which is extremely excellent in high frequency characteristics and has good yield, and a manufacturing method of the common mode noise filter.SOLUTION: A common mode noise filter of the invention includes at least: a first insulation layer 11a including glass and an inorganic filler and having multiple blow holes therein; a pair of coil conductors 12 which are disposed so as to face each other on front and rear surfaces of the first insulation layer 11a; and oxide magnetic body layers 15 disposed above and below the first insulation layer 11a where the pair of coil conductors 12 are disposed. In the common mode noise filter, second insulation layers 11b, 11c, each of which includes glass and an inorganic filler and has multiple blow holes therein, are provided between the first insulation layer 11a where the pair of coil conductors 12 are disposed and the oxide magnetic body layers 15. |
