PROBLEM TO BE SOLVED: To improve the usability of an operator by making a magnetism measuring device itself have an extremely compact and simple structure. SOLUTION: A very weak magnetic field which is emitted from a diagnosis region of a patient P who is mounted on a bed 3, is measured by this magnetism measuring device using a very weak magnetic field measuring sensor 2a. In this case, the measuring device has a first frame 5a which is arranged above the body surface side of the patient P and extends to one side surface 3a side in the longitudinal direction of the bed 3 along the subject mounting surface 3b of the bed 3, and a second frame 5b which extends from the side end section of the one side surface 3a side of the first frame 5a downward along the one side surface 3a, and a Dewar 2 which is constituted by housing the very weak magnetic field measuring sensor 2a in the first frame 5a and the second frame 5b, and a moving-supporting mechanism 4 which movably supports the Dewar 2 in the body axial direction of the patient P, in the lateral direction of the bed 3, and in the vertical direction, are provided.
