<p>Provided is a parting film (1) that is for a step for producing a ceramic green sheet and that is provided with a substrate (11) and a parting agent layer (12) provide to one side of the substrate (11), wherein the parting agent layer (12) is the curing product of a parting agent composition containing a silicone component and an active-energy-ray-curable component, the arithmetic mean roughness (Ra) of the parting agent layer (12) at the surface on the reverse side from the substrate (11) is no greater than 8 nm, the greatest protrusion height (Rp) is no greater than 50 nm, the elasticity measured by means of a nanoindentation test of the parting agent layer (12) is at least 4.0 GPa, the arithmetic mean roughness (Ra) of the substrate (11) at the surface at the reverse side from the parting agent layer (12) is 5-50 nm, and the greatest protrusion height (Rp) is 30-500 nm. By means of the parting film (1) for a step for producing a ceramic green sheet, it is possible to prevent/suppress the occurrence of defects such as thickness unevenness and pinholes in the ceramic green sheet, and furthermore the parting properties of the ceramic green sheet are excellent.</p> |
