In this study, in order to clarify the local inhomogeneity of high-T_c superconducting tape wires, we applied the object detecting model by deep learning to the results of reel-type magnetic microscopy observations. We have succeeded in visualizing current blocking obstacles in long REBCO tapes, and examined the effect on the current transporting performance of the tape.
