Abstract
A superconducting transistor with superior withstand voltage having source region and a drain region formed of oxide superconductors 3, a PrBa.sub.2 Cu.sub.3 O.sub.7-x layer 2 or an ScBa.sub.2 Cu.sub.3 O.sub.7-x layer 2 forming an intermediate region sandwiched by the source and drain regions. The regions are disposed on a substrate 1. An insulation layer 4 is disposed on the intermediate region. A transistor uses the intermediate region as an insulator when the gate is turned off, and as a superconductor when the gate is turned on.
