Disclosed is an electrochemical element electrode manufacturing method comprising a step of preparing a sheet-shaped collector (4) having a plurality of protrusions (4A) of a height of 3 µm to 10 µm on the surface, and a step of forming an active material having a laminated structure on each of the individual protrusions (4A) of the collector (4). The active material forming step includes a first layer evaporating step of making an evaporated deposition material incident on the surface of the collector (4), from a direction inclined with respect to the normal line (H) of the collector (4), thereby to form a first layer (101a), which is positioned on the side closest to the collector, of each active material, on each protrusion (4A), and a second layer evaporating step of making the evaporated deposition material incident on the surface of the collector (4), from a direction inclined oppositely to the incidence direction of the deposition material at the first layer evaporating step with respect to the normal line of the collector (4), thereby to form a second layer (102a) on at least a portion of the first layer (101a). At the first layer evaporating step, the evaporation is performed by moving the collector (4) in the direction to reduce the incidence angle (?) of the deposition material with respect to the normal line (H) of the collector (4). |
