This　work　reports　the　grain　boundary　character　distribution　(GBCD)　on　a　statistical　meaning　of　phase　boundaries　that　are　between　Nd2Fe14B　and　thin-layer-like　Nd-rich　phases　in　a　sintered　NdFeB　magnet.　In　the　low-textured　sample,　the　phase　boundaries　are　divided　into　preferred　phase　boundaries　(with　a　preferred　misorientation　of　31　degrees/[001]　across　the　boundary　plane)　and　random　phase　boundaries.　By　the　five　parameter　analysis　(FPA)　method,　the　orientations　of　phase　boundaries　as　well　as　the　subsets　are　textured.　The　correlation　between　the　GBCDs　and　magnetic　properties　is　suggested　via　the　illustrated　anisotropic　features　at　phase　boundary　positions.
