Electrode active material layer manufacturing device, and electrode active material layer manufacturing method employing same

A production apparatus of an electrode active material layer, comprising:

• a feeding unit that feeds granulated particles containing an electrode active material and a binder;
• a conveying unit that conveys the granulated particles that have been fed from the feeding unit;
• a support unit that supports the granulated particles that have been conveyed by the conveying unit;
• a squeegee unit that is disposed to be spaced above the support unit and that levels the granulated particles to form a granulated particle layer;
• a rolling unit that rolls the granulated particle layer to form an electrode active material layer;
• and
• a pair of stock guide units each having a plate shape;
• wherein:
• the paired stock guide units each independently are disposed to be parallel to side surfaces of the squeegee unit;
• and
• the paired stock guide units are disposed so that an upstream end portion of the stock guide unit is located upstream of a position of a gap portion between the support unit and the squeegee unit, so that a downstream end portion of the stock guide unit is located downstream of the position of the gap portion, and so that a distance between side surfaces of the paired stock guide units is equivalent to a width of the electrode active material layer.
