Abstract

A multilayer substrate includes at least three coil conductors respectively patterned on different surfaces of a first main surface of a laminated body, a second main surface of the laminated body, and laminated interfaces of insulating base materials and that are arranged in a lamination direction. The at least three coil conductors include first and second coil conductors, and are connected in series between first and second external electrodes. A surface at which another coil conductor is provided is not interposed between two surfaces at which the first and second coil conductors are provided, respectively. Further, the first and second coil conductors are directly connected to the first and second external electrodes, respectively, without another coil conductor interposed therebetween.
