Abstract
A coil device has a core including a winding core portion and a flange portion formed on an X-axis-direction end portion of the winding core portion, a coil portion formed by wires being wound around the winding core portion, and terminal electrodes provided on the flange portion. Leadout portions of the wires are respectively connected to the terminal electrodes. A main protuberance having a protuberating shape is formed on an upper surface of the flange portion. The first and second leadout portions of the wires are connected to the first and second terminal electrodes outside the main protuberance in the X-axis direction.
Claims20
A coil device comprising:
- a core including a winding core portion and a flange portion at an end portion of the winding core portion in a first direction;
- a coil portion (i) comprised of wires wound around the winding core portion and (ii) having a coil axis in the first direction;
- and
- spaced terminal electrodes on the flange portion, leadout portions of the wires being connected to the terminal electrodes, wherein
- the flange portion has (i) a first, substantially flat, non-inclined surface that bears the terminal electrodes and (ii) a main protuberance that (a) is adjacent to the first surface and (b) extends outwardly from the first surface in a direction perpendicular to the first surface;
- and
- the leadout portions of the wires are connected to the terminal electrodes at the first surface such that the leadout portions are outward of the main protuberance in the first direction.
