Abstract: In a method for manufacturing a laminated coil component, in which a laminated coil component is manufactured by laminating insulator sheets in order on which conductors having predetermined patterns are formed, the insulator sheets are laminated such that a distance in a lamination direction between a first lead-out conductor laminated first and a first coil conductor laminated next is larger than a distance in the lamination direction between a second lead-out conductor laminated last and a second coil conductor laminated immediately before the second lead-out conductor.

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.

Abstract: A multilayer coil component includes an element body, first and second coils, and a pair of external electrodes. The element body includes a plurality of insulator layers laminated in a first direction. The element body has a pair of end surfaces opposing each other in a second direction orthogonal to the first direction. The first coil and the second coil are disposed in the element body and respectively have coil shafts along the second direction. The pair of external electrodes are disposed on the pair of end surfaces and electrically connected to both ends of the first coil and the second coil. The first coil includes a first conductor layer, a second conductor layer, and a first through hole conductor. The coil shaft of the first coil is disposed inside the second coil.

Abstract: An electronic component includes a body and a pair of terminal electrodes. The body has a pair of end faces opposing each other in a first direction, a pair of main faces opposing each other in a second direction, and a pair of side faces opposing each other in a third direction. One of the main faces serves as a mounting face. A clearance in the first direction between an end edge of a conductive resin layer and the end edge of a base metal layer at an end portion of the one of the main faces in the third direction is longer than a clearance in the first direction between the end edge of the conductive resin layer and the end edge of the base metal layer at a central portion of the one of the main faces in the third direction.

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.
