Abstract
Provided is a cut sheet having sufficient water resistance and having fewer sharp protrusions in the end face despite including a large amount of inorganic particles and a method of reducing cuts. The cut sheet is formed of a resin composition including inorganic particles of 50% by mass or larger relative to the total mass of the composition and a thermoplastic resin. The cut sheet has a water absorption rate of 10% or lower measured in accordance with JIS K-7209. The actual occupancy rate of the exposed area of the inorganic particles is lower by at least 2% than the theoretical occupancy rate of the area of the inorganic particles in at least one end face.
