<P>PROBLEM TO BE SOLVED: To provide a separator exerting optimum seal performance. <P>SOLUTION: A seal line L is formed into a shape having circular arcs Ac each having a center at each corner part located inside the seal line L, and formed by connecting the circular arcs Ac adjacent to each other through a circular arc Am having the center located outside the seal line L. By forming such a seal line, contact pressure generated by fastening in assembly can be dispersed, whereby sufficient seal performance can be exerted without breaking a polymer film. <P>COPYRIGHT: (C)2007,JPO&INPIT |
