Abstract
Provided is a magnetic field measuring device which has good temperature stability and which enables an improvement by making it possible for the sensitivity of a Hall element, a magnetic impedance (MI) element or a magnetic resistance (MR) element, which are conventionally used extensively, to be set freely. This magnetic field measuring device comprises: a temperature maintaining means for maintaining an extremely low temperature state in which a superconductor adopts a superconducting state; a magnetic sensor which is provided inside the temperature maintaining means to detect a magnetic field; and a magnetic field space forming means for forming a magnetic field space specific to the superconducting state, by adopting a superconducting state inside the temperature maintaining means; wherein the magnetic sensor is disposed in the magnetic field space.
