The method of making an electrochemical capacitor electrode in accordance with the present invention comprises a coating liquid preparing step of preparing a porous layer forming coating liquid containing a solid component including a porous particle having an electronic conductivity and a binder adapted to bind the porous particle, a liquid adapted to dissolve or disperse the binder, and an aggregate made of the solid component, such that the aggregate has a degree of dispersion of 10 to 200 mum in the coating liquid; a porous layer forming step of applying the porous layer forming coating liquid onto a surface of a collector and then removing the liquid so as to form a porous layer; and a pressing step of pressing the aggregate against the collector by pressing the collector and the porous layer, so as to form a depression and a projection on the surface of the collector formed with the porous layer. This method can make an electrochemical capacitor electrode having a fully reduced internal resistance and a sufficient electrode characteristic.
