<P>PROBLEM TO BE SOLVED: To provide a double-sided mold release film for molding a green sheet of SOFC in which surface defects and foreign matter are extremely small, fixation (blocking) to the back thereof after molding and fracture due to fixation can be prevented, unevenness of the end faces is less likely to occur, and the vicinity of the winding core is less likely to collapse in the shape of bamboo shoots by a small impact during conveyance and transportation. <P>SOLUTION: The mold release polyester film used for molding a green sheet that is used as the electrolyte of a fuel cell has a silicon release layer on both surfaces of the polyester film. After the mold release polyester film is heat treated at 180°C for 10 minutes, the amount of oligomer on at least one surface (A) of the mold release layer is 3.0 mg/m<SP POS="POST">2</SP>or less. <P>COPYRIGHT: (C)2013,JPO&INPIT |
