Abstract
An electromagnetic coil includes a conductor winding 12a formed by winding a conductor 12b a plurality of times about a predetermined axis, and a ceramic layer 12c formed through thermal spraying on an axial end surface of the conductor winding 12a, and having a flattened surface. A maximal value t12 of thickness of the ceramic layer 12c is set to three times or less a maximal value t11 of depth of the recesses formed at the surface of turns of the conductor 12b at the axial end surface.
