摘要:
A release film that can be used as a carrier film for a green sheet used in a laminated ceramic capacitor is provided. The release film includes a base material having both major surfaces, a releasing agent layer provided on one major surface of the base material, and an antistatic layer provided on the other major surface of the base material, wherein the releasing agent layer and the antistatic layer are mainly composed of the same material, and when the surface roughness of the outer surface of the releasing agent layer is defined as Ra1 [nm] and the surface roughness of the outer surface of the antistatic layer is defined as Ra2 [nm], the relations of Ra1≦15 and Ra1≦Ra2 are satisfied. The release film is capable of preventing occurrence of blocking when being wound in a rolled form for storage and generation of static electricity when being unwound.
