Abstract

PURPOSE:To increase transition current with small element size by providing grooves or hole sections with weak coupling sections to weakly couple upper and lower superconductor thin films crossed each other through an insulator film having grooves or holes. CONSTITUTION:A separate belt-shaped superconductor thin film 3 having the same-shaped grooves as those of grooves 6 (or holes) is provided on a belt- shaped superconductor thin film 2 provided on a substrate 1 so that the films 2 and 3 may cross each other through an insulator layer 4 and a weak coupling section 5 coupling upper and lower superconductor thin films by crossing the thick side of the exposed insulator layer at the grooves is provided on te film 3. In this way, transition current can be increased by leaving the size of a junction element small.
