PROBLEM TO BE SOLVED: To provide biological magnetic field measurement equipment that prevents water drops from upper part of cryostat. SOLUTION: This biological magnetic field measuring equipment is provided with a super conductive quantum interference device and detecting coils, plural number of fluxmeters that detect magnetic field generated by the object, cryostat 2 to maintain the plural number of fluxmeter by liquid cooling media, and moisture-absorbing parts 903-1, 903-2 arranged in upper or side position of the cryostat or parts 904-1, 904-2 for heating a part of the cryostat. The water drops generated by condensation of vapor on the cryostat are absorbed. |
