1. A multilayer substrate comprising:
a laminated body including a plurality of insulating base materials having thermoplasticity that are laminated together, the laminated body including a first main surface and a second main surface that are opposed to each other in a lamination direction of the insulating base materials;
a first external electrode and a second external electrode that are provided on the first main surface; and
at least three coil conductors that are respectively patterned on a plurality of different surfaces of the first main surface, the second main surface, and laminated interfaces of the plurality of insulating base materials and that are arranged in the lamination direction, the at least three coil conductors including a first coil conductor and a second coil conductor, the at least three coil conductors being connected in series between the first external electrode and the second external electrode; wherein
a surface of the plurality of different surfaces at which another coil conductor is provided is not interposed between two surfaces of the plurality of different surfaces at which the first coil conductor and the second coil conductor are provided, respectively;
the first coil conductor and the second coil conductor are directly connected to the first external electrode and the second external electrode, respectively, without another coil conductor interposed therebetween; and
a distance between the surface at which the first coil conductor is provided and the surface at which the second coil conductor is provided is smaller than a distance between surfaces at which other coil conductors adjacent to each other in the lamination direction are provided.
