Abstract

PURPOSE:To prevent a component from being influenced by a magnetic flux from the outside by a method wherein the component constituting an electric circuit is surrounded by a loop-shaped superconducting conductor so that a diamagnetic current which is sufficient to prevent an invasion of the magnetic flux can flow. CONSTITUTION:A loop-shaped superconducting conductor 3 which surrounds a component 2 mounted on a printed wiring board 1 and constituting an electric circuit is provided. When the electric circuit is operated, an electric current flows, and a magnetic flux is generated and interlinked with the component 2. Since the component 2 is surrounded by the loop-shaped superconducting conductor 8, a diamagnetic current flows to the loop-shaped superconducting conductor 8 when the magnetic flux is going to invade; the magnetic flux is bent and guided to another route; the component 2 is not influenced by the magnetic flux.
