<p>PROBLEM TO BE SOLVED: To provide a multilayer coil that allows preventing inter-layer peeling occurring at the vicinity of a boundary between a portion where a coil is provided and a portion where the coil is not provided, in the multilayer coil in which the coil is disproportionately provided on an upper side of a laminated body.SOLUTION: A multilayer coil 1 includes a laminated body 20 and a coil 30. The coil 30 is disproportionately provided on an upper side of the laminated body 20, and is composed of a coil conductor and a via conductor. The coil conductor includes a first coil conductor and a second coil conductor. The cross sectional area S2 of a cross section of the second coil conductor orthogonal to an extending direction of the second coil conductor is smaller than the cross sectional area S1 of a cross section of the first coil conductor orthogonal to an extending direction of the first coil conductor. In the multilayer coil 1, a coil conductor 32f located on the lowest side of the laminated body 20 is the second coil conductor, and a lower surface of the laminated body 20 is a mounting surface.</p> |
