PROBLEM TO BE SOLVED: To improve the detecting sensitivity in vital depth direction and the total S/N ratio of a device, and precisely estimate the current source distribution or a plurality of current dipoles within a living body. SOLUTION: A pickup coil array is formed by arranging plural kinds of pickup coils 210 , 211 , 212 mutually differed in at least one of differential order and base line in combination. The pickup coils 210 , 211 , 212 , which are mutually differed, for example, in only differential order or only base line, are separately arranged in different measuring points or arranged in the same measuring point. This device has magnetic field source estimating means 11, 12 for estimating and computing the information for magnetic field source or magnetic field source distribution within a living body on the basis of the detection signals of the pickup coils. The magnetic source estimating means include a means for correcting the effect of magnetic crosstalk between the pickup coils. |
