Electrode manufacturing method

An electrode manufacturing method performed by an electrode manufacturing apparatus for discharging a liquid to form a resin layer or an inorganic layer on an electrode substrate which is being conveyed in a predetermined direction, the electrode manufacturing method comprising:

• detecting, by a plurality of detectors, a plurality of boundaries between regions where an electrode active material layer is formed and regions where the electrode active material layer is not formed on the electrode substrate, the plurality of boundaries being present in the predetermined direction and in a direction intersecting the predetermined direction, the detecting including;
• detecting the boundaries of the electrode active material layer in the predetermined direction;
• and
• detecting the boundaries of the electrode active material layer in the direction intersecting the predetermined direction;
• outputting, in time series, a plurality of pieces of detection information respectively corresponding to the boundaries detected in the detecting;
• and
• controlling, by a controller, a discharge condition of a liquid discharger provided on a downstream side of the detectors in the predetermined direction and discharging the liquid to form the resin layer or the inorganic layer based on combined detection information obtained by combining the plurality of pieces of detection information.
