Claim:
1. A multilayer inductor comprising: a multilayer body having a top and a bottom surface and a plurality of stacked substrate layers disposed therebetween; a first external connection conductor and a second external connection conductor each disposed on the bottom surface of the multilayer body; a coil conductor that includes a plurality of loop-like line-shaped conductors each disposed on one of the plurality of stacked substrate layers and a plurality of interlayer conductors that connect the loop-like line-shaped conductors to each other, respectively; a first connection conductor that electrically connects a first end portion of the coil conductor to the first external connection conductor; and a second connection conductor that electrically connects a second end portion of the coil conductor to the second external connection conductor, wherein the first connection conductor includes a first single linear routing conductor disposed on a substrate layer between the coil conductor and a top surface of the multilayer body, a first interlayer conductor that connects the first routing conductor to a loop-like line-shaped conductor of an uppermost layer of the coil conductor, and a second interlayer conductor that connects the first single linear routing conductor to the first external connection conductor, wherein the substrate layer between the coil conductor and the first linear routing conductor has a thickness greater than a thickness of the substrate layer between two adjacent loop-like line-shaped conductors of the coil conductor.
