PROBLEM TO BE SOLVED: To provide a sheet using an ionomer resin. SOLUTION: The sheet is made by laminating a layer comprising the ionomer resin and carbon black and a film layer peelable with respect to the layer. The volume resistivity value of the ionomer resin layer is 10<SP>5</SP>-10<SP>15</SP>Ω/m<SP>3</SP>. The ionomer resin is a resin wherein between the molecules of an olefin/carboxylic acid copolymer are crosslinked by metal ions. There is no special restriction as metal ions but ions of potassium, sodium, zinc or the like are used and potassium among them is especially suitable because the volume resistivity value of 10<SP>5</SP>-10<SP>15</SP>Ω/m<SP>3</SP>can be obtained.
