1. An apparatus for manufacturing a cell, the apparatus comprising:
a center electrode reel from which a center electrode is to be unwound;
a first heater configured to apply radiant heat to the unwound center electrode;
an upper separator reel from which an upper separator to be laminated on a top surface of the center electrode is to be unwound;
a lower separator reel from which a lower separator to be laminated on a bottom surface of the center electrode is to be unwound;
an upper electrode reel from which an upper electrode to be laminated on a top surface of the upper separator is to be unwound;
a second heater configured to apply radiant heat to the unwound upper electrode;
a lower electrode reel from which a lower electrode to be laminated on a bottom surface of the lower separator is to be unwound;
a third heater configured to apply radiant heat to the unwound lower electrode;
a first temperature sensor configured to measure a temperature of the center electrode;
a second temperature sensor configured to measure a temperature of the upper electrode;
a third temperature sensor configured to measure a temperature of the lower electrode;
a storage unit in which a reference temperature is previously stored; and
a control unit configured to control the first to third heaters.
