Laminated coil component
By optimizing the structure of the stacked coil components and ensuring the coil conductor arrangement area and the spacing between adjacent conductors, the problem of insufficient high-frequency characteristics was solved, and the high-frequency characteristics in the 60GHz band were improved, making it suitable for optical communication circuits.

Abstract
This invention relates to a stacked coil component, comprising: a stacked body formed by stacking multiple insulating layers along a length direction and having a coil internally therein; a first external electrode and a second external electrode electrically connected to the coil; the coil being electrically connected by multiple coil conductors stacked along the length direction together with the insulating layers; the stacked body having: a first end face and a second end face facing each other in the length direction; a first main face and a second main face facing each other in the height direction; a first side face and a second side face facing each other in the width direction; the first external electrode covering at least a portion of the first end face; the second external electrode covering at least a portion of the second end face; the stacking direction of the stacked body and the coil axis of the coil being parallel to the first main face; the size of the arrangement area of the coil conductors in the stacking direction being 85% or more and 95% or less of the length dimension of the stacked body; and the distance between adjacent coil conductors in the stacking direction being 12 μm or more and 40 μm or less.
