A conduction-cooled superconducting magnet using high-Tc oxide current leads was successfully demonstrated. We succeeded in constructing the (Nb, TiSn multifilamentary superconducting magnet system without liquid helium, which is operated at 11 K in vacuum using a cryocooler and generates a magnetic field of 4.6 T in a 50 mm bore (38 mm room temperature bore). Use of (Bi, Pb)2Sr2Ca2Cu30io current leads effectively contributed to realization of the compact cryostat with large current leads of 500 A.
