NOVELTY - The electrode (2) has a porous portion that is provided with dissolution traces of ostomy particles. The median diameter ratio of active material particle and ostomy particle is specifically defined. The active material particle is formed of conductive polymer. A binder is used as a constituent material of the porous portion. The peak of the peak hole diameter obtained by a mercury-porosimeter measurement is the peak derived from the constituent material of porous portion and the peak derived from the dissolution traces of ostomy particles.    USE - Electrode for electrical storage device such as lithium secondary battery used in portable personal computer, mobile telephone, portable information terminal (PDA), hybrid electric vehicle, electric vehicle, and fuel cell electric vehicle.    ADVANTAGE - The highly efficient positive electrode for electrical storage devices having a high energy density can be manufactured in efficient manner. The gap of active material particles can be extended effectively by forming the dissolution traces of bigger ostomy particles than the gap derived from the active material particle in the electrode for electrical storage devices consisting of porous portion having active material particle. Since electrolyte solution permeates even all the corners of active material particle in the electrode, ion transfer at the time of charging/discharging of active material particle can be performed efficiently. The highly efficient electrical storage device can be obtained with excellent energy density.
