PROBLEM TO BE SOLVED: To provide a multilayer inductor that prevents a conductor pattern from blurring to stably form the conductor pattern with no defects, has an advantage in flattening the multilayer surface and requires no special processing such as laser processing, and can realize miniaturization and high inductance value. SOLUTION: An insulating layer and a conductor pattern are laminated in a proper sequence to form a coil in which the conductor patterns are spirally connected therein. For coil formation, ends of the conductor patterns are sequentially connected at each layer. For the conductor pattern, about a 1/2 turn is to be a unit pattern, its connection positions are two diagonal positions, and a relevant insulating layer 45 is set such that its end part runs up to somewhere around the dead end of the lower unit pattern 25. The leading part of the conductor pattern 23 of the relevant layer is formed so as to overlap the lower conductor pattern 25 evenly. For connecting positions of unit patterns, two positions are set that are in a relation of displacement in an overlapping lamination direction, and these two positions are alternatively repeated every other layer.
