<P>PROBLEM TO BE SOLVED: To provide: a method for forming a sealing film, which does not cause creases (film abnormality) on the surface of the sealing film even when an article to be treated is heated to 100°C or higher after the formation of the sealing film; and a method for manufacturing a lithium secondary battery. <P>SOLUTION: An isocyanate material including either or both of 1,3-bis(isocyanate methyl)cyclohexane and 4,4'-methylene bis(cyclohexyl isocyanate) and an amine material including one or both of 4,4-methylene bis(cyclohexylamine) and 1,3-bis(aminomethyl)cyclohexane are heated separately to generate vapor, and the vapor is allowed together to reach the surface of an object to be treated so that a polyurea film 16a<SB POS="POST">2</SB>is formed. An alumina target is sputtered so that alumina particles reach the surface of the object to be treated on which the polyurea film 16a<SB POS="POST">2</SB>is exposed, thus forming an alumina film 16c<SB POS="POST">2</SB>on the surface of the polyurea film 16a<SB POS="POST">2</SB>. <P>COPYRIGHT: (C)2013,JPO&INPIT |
