<P>PROBLEM TO BE SOLVED: To provide a carbon fiber spun yarn woven fabric that prevents a rupture during coating a catalyst electrode layer and laminating cells, has an impact resistance useful for a gas diffusion electrode, and has a high elongation, and to provide a method for producing the same. <P>SOLUTION: The carbon fiber spun yarn woven fabric has an average thickness of 100 to 1000 μm and the difference between a maximum value and a minimum value of thickness measured in a width direction of the carbon fiber spun yarn woven fabric is 20% or less of the average thickness value. The carbon fiber spun yarn woven fabric has a basis weight of 50-300 g/m<SP POS="POST">2</SP>, an electrical resistance of 150 mΩ/cm<SP POS="POST">2</SP>or less, and an elongation of 15% or more in at least one direction of a longitudinal direction and a width direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
