Abstract
An electromagnetic coil includes a conductor windingformed by winding a conductora plurality of times about a predetermined axis, and a ceramic layerformed through thermal spraying on an axial end surface of the conductor winding, and having a flattened surface. A maximal value tof thickness of the ceramic layeris set to three times or less a maximal value tof depth of the recesses formed at the surface of turns of the conductorat the axial end surface.
