Provided is a multilayer porous suction sheet having an unprecedented structure to prevent contact between a suction object and a suction surface of a suction unit when the sheet is disposed on the suction surface. The porous suction sheet includes a base layer having air permeability and a surface layer disposed on the base layer. The surface layer is made of a porous body composed of resin fine particles that are bonded together, one principal surface of the surface layer opposite to the other principal surface facing the base layer has a surface roughness (Ra) of 1.0 μm or less, and the base layer and the surface layer are coupled together by an air-permeable adhesive layer disposed between the base layer and the surface layer. The base layer and/or the surface layer is made of, for example, ultrahigh molecular weight polyethylene (UHMWPE).
