Electrode manufacturing apparatus

An electrode manufacturing apparatus configured for doping an active material in a strip-shaped electrode precursor having a layer including the active material with alkali metal, the apparatus comprising:

• a doping bath configured to store a solution comprising alkali metal ions;
• a conveyor unit configured to convey the electrode precursor along a path passing through the doping bath;
• a counter electrode unit housed in the doping bath and comprising a conductive base material and an alkali metal-containing plate arranged on the conductive base material;
• and
• a connection unit configured to electrically connect the electrode precursor and the counter electrode unit,
• wherein a thickness of the alkali metal-containing plate becomes greater as a measurement position of the thickness becomes closer to a connection position in which the electrode precursor and the connection unit connect each other.
