PROBLEM TO BE SOLVED: To provide highly safe nonaqueous electrolyte secondary battery having superior cycle characteristics, charge and discharge characteristics and heat radiating characteristics, capable of excellently keeping an initial external form because there is no risk of deformation of the external form caused by a swelling even if charge and discharge is repeatedly carried out. SOLUTION: In this nonaqueous secondary battery, a positive electrode active material layer 1 is disposed face to face with a negative electrode active material layer 2 through a sheet-like porous separator 3, and these positive electrode active material layer 1, the negative electrode active material layer 2, and the porous separator 3 are held between collectors 4 from the outside by the elasticity of the collector having a collector plate 4a and a bonded part 4b. |
