The present invention relates to a termination connection box for a superconducting cable and a leakage inspection method using the same. Specifically, the present invention relates to a termination connection box for a superconducting cable and a leakage inspection method using the same which enable pre-leakage inspection of a sealing unit by welding before laying a superconducting cable and its termination connection box, thereby eliminating a need of dismantling the termination connection box when leakage is detected and enabling precise inspection for whether leakage occurs or a leakage location. 본 발명은 초전도 케이블용 종단 접속함 및 이를 이용한 누설 검사방법에 관한 것이다. 구체적으로, 본 발명은 초전도 케이블 및 이의 종단 접속함 포설 이전에 용접에 의한 실링부의 사전 누설검사가 가능하여 누설 감지시 종단 접속함의 해체가 불필요하고 누설여부 및 누설위치의 정밀한 검사가 가능한 초전도 케이블용 종단 접속함 및 이를 이용한 누설 검사방법에 관한 것이다.
