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 second coil opposes a first coil in a first direction. The first and second coils are positioned between a first conductor and a second conductor in the first direction. The first conductor is adjacent to the first coil in the first direction and overlaps a part of the first coil when viewed from the first direction. The second conductor is adjacent to the second coil in the first direction and overlaps a part of the second coil when viewed from the first direction. The first and second conductors are of a shape extending in a line. Inner regions of the first and second coils include regions not overlapping the first and second conductors when viewed from the first direction.

Abstract: An ESD suppressor is configured including first and second discharge electrodes arranged as separated from each other, and a discharge inducing portion kept in contact with the first and second discharge electrodes so as to connect mutually opposed portions of the first and second discharge electrodes to each other. The discharge inducing portion contains metal particles. The first and second discharge electrodes are located on the coil side with respect to the discharge inducing portion when viewed in a stack direction of a plurality of insulator layers. An element body has a cavity portion located so as to cover the whole of the discharge inducing portion when viewed in the stack direction from the coil side. The cavity portion is in contact with the mutually opposed portions of the first and second discharge electrodes and with the discharge inducing portion.
