The invention discloses a device and a method for sliding type multi-layer magnetic induction tomography. According to the method of sliding type multi-layer magnetic induction tomography, a measured object is put on a plate, a measuring coil array is driven to surround the measured object and the plate, the coil array can slide on the plate so that the central surface of the coil array is corresponding with different faults of the object, one magnetic induction tomography data collection is carried out when the coil array is corresponding with one fault of the object, the conductivity distribution map of the object at the fault is rebuilt through imaging algorithm, data collection can be carried out for a plurality of times by sliding the coil array or plate and a conductivity distribution map at the fault is rebuild each time, a plurality of conductivity distribution maps of the object at adjacent faults are obtained though a plurality of times of data collection and maps rebuilding, and the overall conduct
