COMMON MODE NOISE FILTER
First Claim
1. A common mode noise filter having a filter body that comprises:
- a non-magnetic body;
a first magnetic body and a second magnetic body sandwiching the non-magnetic body; and
a first coil conductor and a second coil conductor of planar shape which are embedded in the non-magnetic body and positioned on the first magnetic body side and second magnetic body side in the non-magnetic body in a manner facing each other in a non-contact state;
wherein the common mode noise filter has a non-magnetic first protective part and second protective part positioned on an outermost side of the filter body in a manner sandwiching the first magnetic body and second magnetic body, where the first protective part and second protective part are made of a non-magnetic material whose strength is higher than the first magnetic body and second magnetic body.
