Abstract
To provide a superconducting device capable of more accurately arranging a non-contact coupling circuit of a superconducting integrated circuit chip and a non-contact coupling circuit of a circuit board. The chip has a first electrode made of a first superconducting material and a first non-contact coupling circuit on a surface thereof. The board has a second electrode made of a second superconducting material and a second non-contact coupling circuit on a surface thereof, and is arranged to face the chip. The second electrode has a protrusion protruding toward the chip. The protrusion includes a flat upper surface. The first electrode has a flat surface and a first recess. The first recess is arranged to face the upper surface to be located inside the upper surface of the protrusion. A third superconducting material connecting the upper surface and the first recess.
