Abstract
In a battery pack (1),a current loop between the positive and negative electrode plates of an electrode assembly passes points P1, P2, P3, P4, P5, P6, P7, P8, P9, P10, P11, P12, P13 and P14 in this order. A line that connects P2 to P3 intersects a line that connects P11 to P12 in the part where the loop passes a sealing plate (12), which is arranged on the top of a battery unit (10). The loop can be divided into loop parts B1 and B2. The part B1 is formed on the exterior side of the battery unit, and extends from the intersection A through a circuit board (20) back to the intersection A. The part B2 is formed on the interior side of the battery unit relative to the intersection A. The current flows counterclockwise and clockwise in the parts B1 and B2, respectively.
