Abstract
The present invention provides a grinding sheet wherein the width of the ridge in the pattern of abrasive layer is larger than the width of the recess formed between the adjacent portions of the ridge. Its shape is suitable to carry out uniform treatment without causing the workpiece to drop into the recess between ridge portions of the pattern of abrasive layer even when the workpiece is swung while the grinding sheet is rotated during grinding operation.
