Claims

[Scope of utility model registration request]

In a coil bobbin that has a sealed structure by molding a wound coil bobbin with a sealing resin, the coil bobbin has a protrusion and a small protrusion formed lower than the protrusion, separating the protrusion and the recess, on the outer surface of the coil bobbin. A coil bobbin characterized by having a plurality of parts.
