Abstract: A structure and a method of manufacturing a power storage device with high energy density are provided. An air electrode includes a first current collector; a second current collector having a projecting structure, in contact with the first current collector; and a catalyst layer having 1 to 100 graphene films. Accordingly, the surface area of the air electrode can be significantly large due to an effect of the second current collector, and further, the graphene film can produce a catalytic reaction without using a catalyst such as a noble metal; thus, by employing a structure in which the catalyst layer is provided on the second current collector, the energy density of the power storage device can be improved.
