Abstract: PURPOSE: A device for measuring magnetism in a living body is provided to improve reliability on a device and reduce price of the device by simplifying the driving circuit of SQUID(Superconducting Quantum Interference Device), to improve reliability on a sensor by integrating a detecting coil on the same substrate with the SQUID and to easily replace the sensor by modulating the sensor. CONSTITUTION: Flat typed deviation measurer(4) and magnetometer(5) are used as a standard channel(3) other than a signal channel(2) using the flat typed deviation measurer for improving noise ratio for signal. Therefore, the signal channel measures the magnetic field signals generated from a human body and from outside while the standard channel measuring the magnetic field signals from outside for improving the noise ratio by selecting an adaptive filtering, which subtracting the output of the standard channel from the output of the signal channel. Two sensors are attached in an epoxy block(7) toward x and y directions each for replacing the sensors in the epoxy block while replacing the block in an insert. Also, a heat blocking plate(10) is used for blocking the heat to the insert and a heat exchanging space(11) and helium gas are used for cooling the wire between an SQUID and a driving circuit to minimize the evaporating rate of liquid helium.
