To achieve a nonaqueous electrolyte secondary battery capable of smoothly releasing outside heat generated inside a power generating element accompanying charge and discharge.

In the nonaqueous electrolyte secondary battery fixing with a winding-off tape 2 an outer periphery of a battery element 1 winding around one laminating a cathode electrode and an anode electrode through a separator, the winding-off tape 2 made of metal with high thermal conductivity is used.
