Abstract

A multilayer coil component 1 includes an element body 2 , a coil 5 , a first terminal electrode 3 , a second terminal electrode 4 , a first connecting conductor 6 , and a second connecting conductor 7 . The first connecting conductor 6 extends along a first direction D 1 and has a third side 6 c intersecting with a second direction D 2 and a third direction D 3 in a cross section orthogonal to the extension direction. The coil 5 faces the third side 6 c of the first connecting conductor 6 when viewed from the first direction D 1 , and a side 5 a facing the third side 6 c is parallel to the third side 6 c at the part that faces the third side 6 c of the first connecting conductor 6.

Claims (16)

1 . A multilayer coil component comprising:

an element body formed by laminating a plurality of insulator layers and having a pair of end surfaces facing each other, a pair of main surfaces facing each other, and a pair of side surfaces facing each other, one of the main surfaces being a mounting surface;

a coil disposed in the element body and having a coil axis extending along a first direction in which the pair of main surfaces face each other;

a first terminal electrode and a second terminal electrode connected to the coil and disposed on the mounting surface;

a first connecting conductor disposed outside the coil in the element body when viewed from the first direction and connecting one end of the coil positioned on the other main surface side and the first terminal electrode; and

a second connecting conductor connecting the other end of the coil positioned on the one main surface side and the second terminal electrode, wherein

the first connecting conductor extends along the first direction and has a first hypotenuse intersecting with a second direction as a facing direction of the pair of end surfaces and a third direction as a facing direction of the pair of side surfaces in a cross section orthogonal to the extension direction, and

the coil faces the first hypotenuse of the first connecting conductor when viewed from the first direction and a side facing the first hypotenuse is parallel to the first hypotenuse at a part facing the first hypotenuse of the first connecting conductor.

2 . The multilayer coil component according to claim 1 , wherein

the first terminal electrode has a rectangular shape when viewed from the first direction and is disposed such that each side is parallel to the end surface or the side surface,

the first connecting conductor has at least three sides including the first hypotenuse, and

the two sides of the first connecting conductor other than the first hypotenuse are parallel to the respective sides of the first terminal electrode.

3 . The multilayer coil component according to claim 1 , wherein

the second connecting conductor extends along the first direction and has a second hypotenuse intersecting with the second direction and the third direction in a cross section orthogonal to the extension direction, and

the coil faces the second hypotenuse of the second connecting conductor when viewed from the first direction and a side facing the second hypotenuse is parallel to the second hypotenuse at a part facing the second hypotenuse of the second connecting conductor.

4 . The multilayer coil component according to claim 1 , wherein each of the first connecting conductor and the second connecting conductor has a triangular shape in a cross section orthogonal to the extension direction.
