摘要： Disclosed herein is a coil component that includes an insulating substrate, a first coil part formed on the first surface of the insulating substrate, and a second coil part formed on the second surface of the insulating substrate. At least an innermost turn of the first coil part is radially separated by spiral-shaped slits into three or more conductor parts. At least an innermost turn of the second coil part is radially separated by spiral-shaped slits into three or more conductor parts. Inner peripheral ends of respective innermost to outermost conductor parts of the three or more conductor parts of the first coil part are connected to inner peripheral ends of the respective outermost to innermost conductor parts of the three or more conductor parts of the second coil part.

摘要： Disclosed herein is a coil component that includes a core including a winding core part extending in the x-direction and a flange part, a terminal electrode provided on the flange part, and a wire wound around the winding core part and connected to the terminal electrode. The terminal electrode does not overlap the winding core part in the y-direction. The wire includes a wound part wound around the winding core part and a drawn part drawn from the wound part, running across the winding core part in the z-direction and connected to the terminal electrode. The core has a positioning part that positions the drawn part of the wire in the y-direction.

摘要： Disclosed herein is a coil component that includes a magnetic core having first and second through holes extending in a first direction and arranged in a second direction perpendicular to the first direction, and a conductive plate including first and second body parts inserted respectively through the first and second through holes. The magnetic core includes a middle leg part positioned between the first and second through holes, a first outer leg part positioned on an opposite side to the middle leg part across the first through hole, and a second outer leg part positioned on an opposite side to the middle leg part across the second through hole. Area of each of the first and second outer leg parts defined by the first and second directions is larger than that of the middle leg part.

摘要： Disclosed herein is a coil component that includes: a drum core including a first flange portion, a second flange portion and a winding core portion positioned between the first and second flange portions; a plurality of coated conductive wires forming a first winding layer wound around the winding core portion and a second winding layer wound around the winding core portion with an intervention of the first winding layer; and a resin coating layer covering the coated conductive wires. A maximum space between the coated conductive wires in the first winding layer is narrower than a diameter of the coated conductive wires.
