Abstract: An electronic component includes a multilayer body constituted by insulator layers that are laminated in a laminating direction, a primary coil including one or more primary coil conductor layers, a secondary coil including one or more secondary coil conductor layers, and a tertiary coil including one or more tertiary coil conductor layers. The primary coil conductor layers, the secondary coil conductor layers, and the tertiary coil conductor layers are arrayed in the laminating direction. The primary coil, the secondary coil, and tertiary coil constitute a common mode filter, and intervals between two among the one or more primary coil conductor layers, the one or more secondary coil conductor layers, and the one or more tertiary coil conductor layers, every two of those being adjacent to each other in the laminating direction, are not even.

Abstract: An electronic component includes a main body formed from an insulative material, coil conductors, outer electrodes provided on a surface of the main body, and outer pads. Each coil conductor is constituted by a spiral-shaped coil portion and a lead portion connected to the coil portion and extending linearly. The outer pads connect the lead portions to the outer electrodes. At a contact point that connects one of the coil portions to their corresponding one of the lead portions, an angle formed by the coil portion and the lead portion is an obtuse angle.

Abstract: A transformer includes a first coil spiraling inwardly in a second direction. A second coil spirals along the first coil on the outside relative to the first coil. First and second external electrodes are provided in third and fourth directions relative to a first line passing through a gravity center of the first coil and an outer end thereof, respectively, the third direction being perpendicular to the first line, and the fourth direction being opposite thereto. First and second lead-out conductors are connected to the outer end of the first and the second coil, respectively, and electrically connected to the first and the second external electrodes, respectively. Both coils spiral along each other throughout their lengths. By spiraling in the second direction, the first coil is, at the outer end, oriented in a fourth direction.
