Electrode for power storage device, power storage device, and method for manufacturing electrode for power storage device

A method for manufacturing an electrode for a power storage device, comprising the steps of:

• kneading carbon nanotubes and an ionic liquid to produce a kneaded material;
• and
• charging said kneaded material into pore portions of a three-dimensional network metal porous body having a plurality of pore portions, wherein
• in pore portions exposed at a surface of said three-dimensional network metal porous body, of said plurality of pore portions, a ratio (d/D) between a pore portion diameter (D) in a first direction within the surface of said three-dimensional network metal porous body and a pore portion diameter (d) in a second direction orthogonal to said first direction within the surface of said three-dimensional network metal porous body is in a range of 0<d/D<1, and
• pore portions in said range account for more than or equal to 95% and less than or equal to 100% of the pore portions exposed at said surface.
