    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 conductor component includes an element body, an internal conductor, and an external electrode. The external electrode includes a sintered metal layer. The sintered metal layer is disposed on an end surface, a pair of side surfaces, a first main surface, and a second main surface of the element body. An electrode length, which is a length in the first direction from an edge of the sintered metal layer to a reference plane including the end surface, at a central portion of the first main surface in the third direction, is shorter than the electrode length at each of the ridge portions. The electrode length at a central portion of each of the pair of side surfaces in the second direction is equal to or less than the electrode length at each of the ridge portions.
