PROBLEM TO BE SOLVED: To provide a magnetic measuring device capable of measurement even if a device having a refrigerant and a magnetic sensor is inclined and toppled down sideways and easy in assembling. SOLUTION: On the inside of a heat insulating vessel 14 vacuum-packed by inserting a heat insulating material 20 between an outer vessel 15 and an inner vessel 16, a refrigerant 23 is put in a refrigerant vessel 26 having the same shape as that of the vessel 14, and a large number of magnetic sensors 5 are arranged in a domed position corresponding to its bottom part 18. A small opening part 14 is arranged on the upper end of the refrigerant vessel 26, and in the upper part, the heat insulating vessel 14 and a cover 22 are confined by a packing 21. Thus, bottom parts 17, 18 of the heat insulating vessel 14 has a dome shape for fitting the head part of an examinee, and this device is sometimes inclined and toppled down sideways to apply these parts to the head part, but, at this time, the inside refrigerant 23 does not overflow from the refrigerant vessel 26.
