PROBLEM TO BE SOLVED: To eliminate mutual interferences among coils in a coil array in which more than three coils are employed, without causing overlapping of the adjacent coils. SOLUTION: This imager is provided with more than three coils 1, 2 and 3 arranged close by, capacitors 4, 5 and 6 for connecting the coils which are srespevtively interposed in the coils, parallel connection lines 10 to 13 for connecting the capacitors 4, 5 and 6 in parallel, and neutralizing capacitors 14 to 17 interposed in the connection lines 10-13. A transfer voltage is transferred from both ends of the connecting capacitor 4 of one coil 1 to the connecting capacitors 2 and 3 of the other coils via the parallel connection lines 10 to 13 and the neutralizing capacitors 14 to 17. With this transfer voltage, an induced voltage which one coil allows the connection capacitors 5 and 6 of the other coils 2 and 3 via mutual inductance is cancelled. Accordingly, the freedom of coil arrangement and an S/N ratio can be improved.
