Claim Text:
1. A method for producing a secondary battery, comprising: an electrode plate placing step of placing a predetermined number of positive electrode plates or negative electrode plates on a positive electrode plate or negative electrode plate cassette member; an electrode plate supply step of batchwise supplying the predetermined number of positive electrode plates or negative electrode plates placed on the positive electrode plate or negative electrode plate cassette member to an electrode plate conveying member for positive electrode plates or negative electrode plates; a zigzag folding step of pushing a separator by a plurality of guide members to fold the separator zigzag; a multilayer body formation step of inserting the positive electrode plates placed on the electrode plate conveying member for positive electrode plates and the negative electrode plates placed on the electrode plate conveying member for negative electrode plates into respective furrows of the zigzag-folded separator to form a multilayer body having the positive electrode plates and the negative electrode plates superposed alternately via the separator; a withdrawal step of withdrawing the guide members from inside the respective furrows of the separator; and a pressing step of pressing the multilayer body in a direction in which the positive electrode plates and the negative electrode plates are stacked.
