Abstract: An antistatic sheet capable of improving working efficiency includes a laminated body formed by laminating a polymer gel on an antistatic-treated base sheet, the polymer gel comprising: a polymer matrix obtained by copolymerization-crosslinking of a polymerizable monomer having in its molecule at least one polymerizable carbon-carbon double bond and a crosslinkable monomer having in its molecule at least two polymerizable carbon-carbon double bonds; water having dissolved therein at least polyvinyl alcohol-type polymer; and a polyhydric alcohol other than polyvinyl alcohol-type polymer, wherein the water and the polyhydric alcohol are retained in the polymer matrix, the antistatic sheet having a ground resistance of 1.0×105Ω or more and 1.0×1012Ω or less, and a surface resistivity of 1.0×104Ω/□ or more and 1.0×1012Ω/□ or less as measured with respect to a surface thereof on a side of the base sheet.
