Abstract: Disclosed is a bobbin structure for winding a superconducting wired rod, which can secure a minimum radius of curvature that can prevent a deterioration in mechanical properties and a decrease in the uniformity of electromagnetic force distribution, due to contraction and expansion acting on the wire rod during quenching of the superconducting wire rod, and which also can ensure uniformity of temperature over all portions of the superconducting wire rod by securing a cooling channel required for cooling of the superconducting wire rod.
