Abstract
Provided is a secondary battery having high utilization efficiency per unit volume. The secondary battery includes: an electrode laminate in which a positive electrode layer and a negative electrode layer are laminated on each other through intermediation of an insulating layer; a pair of support plates configured to sandwich the electrode laminate therebetween; and a column body which is sandwiched between the pair of support plates at both ends thereof and adhered to the pair of support plates.

A secondary battery, comprising:
- an electrode laminate in which a positive electrode layer and a negative electrode layer are laminated on each other through intermediation of an insulating layer;
- a pair of support plates configured to sandwich the electrode laminate therebetween;
- and
- a column body which is sandwiched between the pair of support plates at both ends thereof and adhered to the pair of support plates.
A method of manufacturing a secondary battery, comprising:
- laminating a positive electrode layer and a negative electrode layer on each other through intermediation of an insulating layer to provide an electrode laminate;
- sandwiching, between a pair of support plates, a column body at both ends thereof and the electrode laminate;
- and
- performing heating after the sandwiching to deform the column body.
