Abstract: First internal conductors are separated from each other in a first direction. Each of the first internal conductors includes a coil portion and a pad portion having a width larger than a width of the coil portion. The pad portions adjacent to each other in the first direction are connected to each other via a through-hole conductor and overlap each other when viewed from the first direction. When viewed from the first direction, each of the coil portions includes a first portion not overlapping the pad portion adjacent in the first direction and a second portion overlapping a part of the pad portion adjacent in the first direction. A second internal conductor is disposed on the same layer as the second portion and is positioned to overlap a portion of the pad portion adjacent in the first direction not overlapping the second portion when viewed from the first direction.

Abstract: A method of manufacturing a laminated coil component is a method of manufacturing a laminated coil component provided with a laminate obtained by laminating a coil conductor forming a spiral coil and an insulator layer. The method of manufacturing a laminated coil component includes a step of providing a conductor pattern configured to become a coil conductor on a green sheet configured to become an insulator layer, and a step of laminating a plurality of green sheets provided with the conductor pattern. The conductor pattern includes a pair of first side surfaces opposed to each other in an orthogonal direction orthogonal to a laminating direction of the green sheet. At the step of laminating a plurality of green sheets, a depression is formed on at least one of the pair of first side surfaces.
