Further, the release film characterized is in that: the outer surface of the release agent layer has an arithmetic mean rough - ness (Ra2) of 8nm or less and a maximum protrusion height (RP2) of 50nm or less; and the outer surface of the back coat layer has an arithmetic mean roughness (Ra ) of 3 5 to 40nm and a maximum protrusion height (Rp ) 3 of 60 to 500nm. According to the present in­ vention, the occurrence of pinholes or partial thickness irregularities in a green sheet can be minimized.
