To provide the electrode structure for a fuel cell, which can make a power generation efficiency effective, and is costwise favorable in a solid polymer type fuel cell.

As for a second catalyst layer 432, PTFE dispersion solution of 80mg with a weight ratio of 55% is adjusted to the same solution of 79mg by coordinating carbon black carrying platinum with a weight ratio of 20% so as to be mixed with pure water of 40ml and isopropanol of 40ml, so that the mixture is dispersed by the use of an ultrasonic cleaner. As for a first catalyst layer 431, carbon black of 40mg, carrying plattinum with a weight ratio of 40%, is mixed with the PTFE dispersion solution of 29mg so as to allow dispersion solution to be regulated. After an anode side pole joining body and a cathode side pole joining body have been formed, let the cathode side pole joining body and the anode side pole joining body be faced to each other in such a way that respective catalyst layer sides are faced to each other, and a solid polymer electrolytic film is interposed between the aforesaid layers so as to be jointed together. They are then fixed using a press jig so as to be formed into a solid polymer electrolytic film pole joining body by hot pressing them using pressure of roughly 25kgf/cm2 per unit area of the pole joining body at the temperature of around 155°C.
