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: In a multilayer coil component, a plurality of coil conductors are stacked in a coil axis direction. A connecting conductor connects the coil conductors adjacent to each other in the coil axis direction. First, second, and third coil conductors are arranged in order in the coil axis direction. A main body portion extends in a circumferential direction of the coil axis. Pad portions are connected to the main body portion, are connected to the first coil conductor via the connecting conductor, overhang from the third coil conductor in a direction away from the coil axis when viewed from the coil axis direction, and are inclined with respect to a virtual plane orthogonal to the coil axis direction.

Abstract: In the multi-layer coil component, the hole portion is provided in the vicinity of the side surface of the element body, and the distance from the tip position of the external electrode to the hole portion is shorter than the distance from the tip position of the external electrode to the coil. Therefore, when a crack is generated starting from the tip position of the external electrode on the mounting surface, the crack progress toward the hole portion located at a distance closer than the coil. Therefore, in the multi-layer coil component, splitting of the coil due to the crack can be prevented.

Abstract: A multilayer coil component includes: an element body having a pair of first side surfaces opposite to each other in a first direction and a pair of second side surfaces opposite to each other in a second direction orthogonal to the first direction; and a coil disposed inside the element body and having a coil axis extending in a third direction orthogonal to the first direction and the second direction, in which one of the pair of first side surfaces is a mounting surface, and a ratio of a first gap in the first direction between the coil and the mounting surface to a size of the element body in the first direction is 12 to 30% in a cross section viewed in the third direction.
