Title: ELECTRIC ELEMENT
Abstract:
Provided is an electric element whereby difference in characteristics between electric elements is suppressed. The electric element comprises: a substrate including resin layer and a first conductor having a surface coming in contact with the resin layer; and a magnet. The substrate has a smooth first main surface facing the magnet. The first conductor includes a coil that: has a winding axis arranged orthogonal to the first main surface; and is positioned closest to the first main surface side. The coil includes a series of coil conductors having: a first coil surface facing the first main surface; and a second coil surface on the opposite side to the first coil surface. The coil conductors have a non-uniform thickness in the winding axis direction such that the distance between the first coil surface and the second coil surface varies along the winding direction. The difference between the maximum value and the minimum value for the distance between the first coil surface and the first main surface is smaller than the difference between the maximum value and the minimum value for the distance between the second coil surface and the first main surface.
