A cathode catalyst layer (16) includes electron conducting carbon nanotubes (CNTs) (161) having a hollow space formed at an interior. The CNTs (161) are, in a hollow space forming direction thereof, open at a first end and are closed at a second end. The open end (161a) is disposed so as to be in contact with a gas diffusion layer (22). On the other hand, the closed end (161b) is disposed so as to be in contact with a polymer electrolyte membrane (12). Defects are formed on a surface of the CNTs (161). The defects (161c) are formed so as to communicate between an outer surface of the CNTs (161) and the hollow space. Catalyst particles (162) are provided on the outer surface of the CNTs (161), and an ionomer (163) is provided so as to cover the catalyst particles (162).
