The workpiece protection sheet of the present disclosure is used between a suction table and a workpiece in a state where the workpiece protection sheet is sucked to the suction table when the workpiece is pressed on the suction table. The workpiece protection sheet of the present disclosure includes a base layer and an ultrahigh molecular weight polyethylene porous layer, an air permeability in a thickness direction of the workpiece protection sheet measured such that the base layer side is at an upstream side of airflow during measuring is 4000 seconds/100 mL or more as represented by a Gurley air permeability measured according to Method B of air permeability measurement specified in JIS L1096, a suction surface to be sucked to the suction table is composed of the base layer, and a contact surface to be in contact with the workpiece is composed of the ultrahigh molecular weight polyethylene porous layer. With the workpiece protection sheet of the present disclosure, the releasability of a workpiece after pressing is improved.
