摘要

A superconducting magnetism measuring device capable of suitably measuring feeble magnetism generatint at the neck or the waist without requiring the subject to bend forward his neck or waist. A sensor tube (10) is a rectangular tube having a y-direction width of 5 cm through 20 cm and an x-direction width of 5 cm through 20 cm, and its tip end portion (10c) is smoothly curved with the center thereof in the y-direction projecting 0.5 cm through 4 cm beyond its upper and lower ends. Since the tip end surface of the sensor tube (10) can be brought into close contact with the neck or the waist of the subject (H) even if the neck or the waist of the subject is not bent forward, feeble magnetism generating at the spinal cord or the spinal cord nerve can be suitably measured.
