Abstract (en)
[origin: EP2957672A1] Provided is a hard sheet including a non-woven fabric of ultrafine fibers and elastic polymer added into the non-woven fabric. JIS-D hardness of the sheet is 45 degrees or more. R% thereof calculated by R(%) = (D hardness maximum - D hardness minimum) / D hardness average × 100 is 0 to 20%, when a sectional surface of the sheet extending in the thickness direction thereof is evenly divided into three parts corresponding to a first outer layer, an intermediate layer, and a second outer layer in order from any one surface side of the sheet; JIS-D hardness measurements are made at six points being three arbitrary points each on the first outer layer and on the intermediate layer; and then the JIS-D hardnesses obtained are used for the calculation. In the sheet, the total content of ions capable of changing the pH of water is 400 µg/cm 3 or less.
