    Abstract: A multilayer coil component 1 includes an element body 2, a coil 10, and a pair of terminal electrodes 3. The element body 2 has a groove portion 20 provided on a main surface 2c. The groove portion 20 is disposed between the pair of terminal electrodes 3 and extends over one side surface 2e and the other side surface 2f. The depth of the groove portion 20 in the direction in which the main surface 2c and a main surface 2d, which are a pair, face each other is smaller than the thickness of each of the pair of terminal electrodes 3 in the facing direction.

    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 D1 and has a third side 6c intersecting with a second direction D2 and a third direction D3 in a cross section orthogonal to the extension direction. The coil 5 faces the third side 6c of the first connecting conductor 6 when viewed from the first direction D1, and a side 5a facing the third side 6c is parallel to the third side 6c at the part that faces the third side 6c of the first connecting conductor 6.

    Abstract: A multilayer coil component includes: an element body including a plurality of insulator layers that are laminated; a coil; and a pair of external terminals. The element body has a rectangular parallelepiped shape. The element body includes a pair of main surfaces opposing each other in a first direction, a pair of end surfaces opposing each other in a second direction, and a pair of side surfaces opposing each other in a third direction. The pair of external terminals are separated from each other in the second direction. The pair of external terminals are embedded in the element body apart from the pair of end surfaces and the pair of side surfaces. Each of the pair of external terminals includes an exposed surface exposed from one of the main surfaces and an inner surface disposed in the element body. The inner surface includes a depression or a protrusion.

    Abstract: A multilayer coil component includes an element body, a coil disposed in the element body, and a terminal electrode disposed on the element body. The element body has a first side face and a second side face, a first end face and a second end face, and a first main face and a second main face. The terminal electrode includes a first electrode portion and a second electrode portion. The first electrode portion has a first exposed face exposed on the first main face. The second electrode portion has a second exposed face exposed on the first end face. The first exposed face and the second exposed face are adjacent to each other interposing a ridge portion. The first exposed face is separated from an outer edge of the first main face. The second exposed face is separated from an outer edge of the first end face.

    Abstract: A multilayer coil component includes an element body, a coil, and a terminal electrode. The element body includes a first main face, second main face, first end face, second end face, first side face and second side face. The terminal electrode is connected to the coil. The terminal electrode includes a main-face electrode portion provided on the first main face. The coil includes a plurality of coil conductors. The plurality of coil conductors includes a first coil conductor disposed closest to the first main face to oppose to the main-face electrode portion and a second coil conductor disposed closer to the second main face than the first coil conductor. The first coil conductor has a width narrower than a width of the second coil conductor. The first coil conductor has an aspect ratio higher than an aspect ratio of the second coil conductor.
