    摘要: Each of collectors 22 of an electrode structure 20, which partially constitutes a polymer electrolyte fuel cell, is formed from a metal lath MR having a large number of through-holes. A stopping portion 22a in which the through-holes are reduced in diameter is formed at a peripheral end portion of the collector 22. The peripheral end portion of the collector 22 is folded; subsequently, the folded peripheral end portion is pressed, thereby forming the stopping portion 22a. A resin seal portion 23 for sealing introduced fuel gas and oxidizer gas is formed integrally with the stopping portions 22a by insert molding which is performed such that an injected molten resin encloses the stopping portions 22a. The resin seal portion 23 formed integrally with the stopping portions 22a can reliably prevent inflow of the molten resin toward central portions of the collectors 22.
