When a conventional sensor or tag is sandwiched by a plurality of metal planes, the condition is deteriorated and the sensitivity is lowered. Provided is multiplane imaging system using MISEMAS (Multi-Image Effect and Separation Method for Magnetic Sensor and Tag) in which the sensitivity is not lowered, but rather enhanced, and it is possible to separate and select each of the tags without causing interference with adjacent sensor coils SC 1 , SC 2 , SC 3 , SC 4 or tags R 1 , R 2 , R 3 , R 4 , thereby enabling an effective use of a current on the metal surface and a magnetic path. |
