(54) NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, VEHICLE, AND DEVICE USING BATTERY


(57) Disclosed is a nonaqueous electrolyte secondary battery (100) which comprises a flat wound electrode body (120) wherein a positive electrode plate (121), which comprises a positive electrode collector foil (122) and a positive electrode active material layer (123), and a negative electrode plate (131), which comprises a negative electrode collector foil (132) and a negative electrode active material layer (133), are wound up with a separator (141) being interposed therebetween. The positive electrode plate (121) has a collector portion covering layer (125) that has electrical insulation properties and covers at least a part of a counter collector portion (121m1) in the longitudinal direction in a positive electrode collector portion (121m). The collector portion covering layer (125) covers at least a counter collector innermost half-cylinder portion (121m1ar) which forms the innermost part of the counter collector portion (121m1) and has a half-cylindrical shape.
