发明名称 COMMON MODE NOISE FILTER AND MANUFACTURING METHOD THEREOF
摘要 A common mode noise filter includes: a laminated body; and a first and second coil conductors that are formed inside the laminated body and face each other in a first direction, wherein the first coil conductor has a first surface facing the second coil conductor; the second coil conductor has a second surface facing the first surface; a distance between ends of the first and second surfaces in the first direction is longer than a distance between centers of the first and second surfaces in the first direction; the first and second surfaces have corners each formed into an arcuate shape in a cross section; and a relationship between a height h in the first direction and a width w in a second direction perpendicular to the first direction is h≧w in a cross section of each of the first and second coil conductors.
