PURPOSE:To shorten distances among weak combining sections, and to remove electrostatic capacitance by using sections, where a plurality of superconductor films are collected and coupled mutually at some angle, as the weak coupling sections. CONSTITUTION:An etching-resistant film 41 is applied onto a substrate as a foundation layer 10, and a semi-columnar surface shaping section 50 is applied and formed extending over the upper section of the substrate and the upper section of the film 41. Sections except a substrate section coated with the etching-resistant film 41 are etched, and shaped to the state shown in solid lines from the original state shown in dotted lines. The film 41 and a columnar section 54 are removed through etching, and first and second superconductors 23, 24 are applied onto a substrate surface containing the exposed surface of a semicircular intermediate section 53, thus acquiring Josephson junction element structure. Accordingly, the superconductor films 23 and 24 obtained are collected and coupled mutually at the positions of P1 and P2 to form a weak coupling section, and a connecting area is determined by the thickness of the films and crossed angles, and takes a small value. |
