<p><P>PROBLEM TO BE SOLVED: To make areas of a positive electrode uncoated part and a negative electrode uncoated part as small as possible and make areas of a positive electrode coated part and a negative electrode coated part as large as possible. <P>SOLUTION: A positive electrode coated part 12a in which a positive electrode active material is coated on a positive electrode metal foil 121 and an uncoated part 12b are formed on a positive electrode 12. A negative electrode coated part and an uncoated part 13b are formed on a negative electrode 13 as well. An area of the negative electrode coated part 13a is larger than an area of the positive electrode coated part 12a and a width H3 of the negative electrode uncoated part is shorter than a width H1 of the positive electrode uncoated part. Collector terminals 31 are connected to respective uncoated parts and the width H1 of the positive electrode uncoated part 12b and the width H3 of the negative electrode uncoated part 13b respectively are equal to or less than double length of a length H of a connection part 32 in the thickness direction. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
