<P>PROBLEM TO BE SOLVED: To always stabilize a characteristic of a product by reducing fluctuation of a linkage amount of magnetic flux and a coil, which is to be discharged from a magnetic gap. <P>SOLUTION: A coil component includes: first and second two-divided magnetic cores 9 and 10 in the same shapes, which consist of disk-like back magnetic boards 14; cylindrical legs 15 which rise in cylindrical shapes in a vertical direction of disk faces from an outer periphery, and middle magnetic legs 11 rising in the vertical direction from the disk faces of the back magnetic boards 14 in the centers of the cylindrical magnetic legs 15; winding sections 12 wound around the middle magnetic legs 11; and connection terminal sections connected to ends of the winding sections 12. First and third arc wall sections 17 and 19 of the first divided magnetic core 9 are permitted to abut against second and fourth arc wall sections 18 and 20 of the second divided magnetic core. Second and fourth arc wall sections 18 and 20 of the first divided magnetic core 9 are made to abut against third and first arc wall sections 19 and 17 of the second divided magnetic core 10 to form a closed magnetic circuit, and connection terminal sections are pulled out from a window section formed by allowing notch sections 16 to face each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
