Claims

[Scope of utility model registration request]

In an electromagnetic coil in which a coil is wound around a bobbin having flange portions at both ends, and the surface layer of the coil and almost the entire outside of the flange portion is integrally coated with a resin material, a suitable portion of the periphery of each of the flange portions is coated from the end face. An electromagnetic coil characterized in that a through hole or notch is provided toward a surface layer of the coil, and an end surface side of the resin material and a surface layer side of the coil are connected via the through hole or notch.
