Abstract
A laminator is configured for increasing the force of adhesion between an electrode and a separator upon forming a unit structural body. The laminator is configured for heating a unit structural body sheet that includes an electrode and a separator in a stacked state and a press roll having a pair of upper and lower rolls configured to press the heated unit structural body sheet. The press roll is configured to raise its temperature. The average temperature of the press roll is higher than the temperature of the unit structural body sheet.
