열가소성 수지 필름과, 실리콘 수지를 포함하는 수지층(그 수지층을 이형층이라고 칭한다)을 갖는 적층 필름으로서, 상기 이형층이 적층 필름의 적어도 한쪽의 최표층에 있고, 상기 이형층측에서 측정한 압입 탄성률이 100N/㎟ 이상이며, 상기 이형층 표면의 산술평균조도(Ra)가 1∼50㎚인 적층 필름. 점착제에 대한 박리성이나 세라믹 슬러리에 대한 박리성이 뛰어나고, 또한 평활성, 전사성, 내마찰성이 우수한 적층 필름을 제공한다. Provided is a laminated film having a thermoplastic resin film and a resin layer that includes a silicone resin (the resin layer is termed a "mold release layer"), wherein the mold release layer is the outermost layer on at least one side of the laminated film, the elastic modulus, measured from the mold release layer side, is 100 N/mm2 or greater, and the mean surface roughness (Ra) of the mold release layer surface is 1-50 nm. The laminated film has excellent release properties with respect to adhesives and release properties with respect to ceramic slurry, as well as excellent smoothness, transferability, and abrasion resistance.
