PURPOSE: A bobbin is provided to allow the reactor circuit for correcting pin cushion to be easily mounted on a circuit board, while preventing a concentration of heat generated during formation of magnetic fields. CONSTITUTION: A bobbin(160) comprises a first body(161) and a second body(162) connected through connection members(163) in such a manner that the first body and the second body are foldable and separable from each other. The first body and the second body are curved inward. The first body has a coupling protrusion(161b) for coupling with the second body. The second body has a stopper(162b) formed at the position corresponding to the coupling protrusion of the first body so as to permit the coupling protrusion to be inserted into and get caught at the stopper. The second body has a fixing protrusion(162c) arranged on the outer surface of the second body.
