PROBLEM TO BE SOLVED: To prevent a sensor and an amplifier, or the like from being damaged without making an external magnetic field intrude into a main shield chamber. SOLUTION: In this magnetic measurement device, a sensor part 3 is arranged inside respectively main and sub-magnetic shield chambers 4a and 4b, the weak magnetic signals of a testee body 1 detected by the sensor part 3 are digitized by a data analyzer 10 arranged on the outside of the shield chamber and an image processing is performed. In this case, each magnetic shield chamber is divided into at least two chambers and the respective chamber are turned to the main shield chamber 4a where a living body (testee body) 1 is arranged an a sub shield chamber 4b to enter before entering the main shield chamber 4a separated by a door provided with a magnetic shield function. |
