Patent ID: 7060388

Claim:
A nonaqueous electrolyte secondary battery comprising: a casing; an electric power generating element comprising a positive plate provided with a positive current collector and a negative plate provided with a negative current collector, said positive plate and said negative plate being laminated on each other with a first separating member interposed therebetween; and an electric conductor comprising a positive conductor member electrically connected to said positive current collector and a negative conductor member electrically connected to said negative current collector, said positive conductor member and said negative conductive member being laminated on each other with a second separating member interposed therebetween; wherein said electric power generating element is housed in said casing, and an outer circumferential surface of said electric power generating element is covered with said electric conductor; and wherein an electric resistance per unit length of said positive conductor member is smaller than an electric resistance per unit length of said positive current collector electrically connected to said positive conductor member, or an electric resistance per unit length of said negative conductor member is smaller than an electric resistance per unit length of said negative current collector electrically connected to said negative conductor member.
