PROBLEM TO BE SOLVED: To provide a sheet for suction used as the means for fixing or moving an article by suction capable of being applied even to a material which requires high precision, is easy to plastically deform or is in the form of a thin leaf. SOLUTION: The sheet for suction is composed of a porous product which is constituted of a mixture of (A) 30-90 pts.wt. ultra-high-molecular weight polyethylene powder having a molecular weight by the viscosity method of >=600,000 and (B) 10-70 pts.wt. polyethylene powder having a melt flow rate of 0.01-30 g/10 min, and is set to have an arithmetic average roughness (Ra) of the surface roughness of <=1 μm at least at its one side, an air flow resistance of 300-1,000 mmAq, and a flexural modulus of 500-5,000 kg/cm2.
