Kind Code:
B2
Abstract:
To provide a laminated coil component having excellent high frequency characteristics.SOLUTION: A laminated coil component 1 includes a laminated body 10 having a plurality of insulating layers laminated in the length direction and having a built-in coil, and a first external electrode 21 and a second external electrode 22. The coil is formed by connecting a plurality of coil conductors 32 laminated in the longitudinal direction together with insulating layers. The laminate includes a first end face 11 and a second end face 12 facing each other in the length direction, a first main surface 13 and a second main surface 14 facing each other in the height direction, and a first side and a second side facing each other in the width direction. The first external electrode and the second external electrode cover at least a part of the first end face and the second end face, respectively. The stacking direction of the laminate and the central axis A of the coil are parallel to the first main surface, and the dimension L3 of the arrangement area of the coil conductor in the stacking direction is 85% or more and 95% or less of the length dimension L1 of the laminate, and the distance D between the coil conductors adjacent in the stacking direction is 12 μm or more and 40 μm or less.SELECTED DRAWING: Figure 3
