1. A battery pack comprising:
a battery cell; a main circuit board electrically connected to the battery cell and extending in a first direction that is a lengthwise direction of the main circuit board; and a flexible circuit board extending in the first direction in parallel with the main circuit board and comprising an external connection terminal located at a position outside the main circuit board in a second direction crossing the first direction,
wherein the main circuit board and the flexible circuit board respectively comprise a plurality of first coupling pads and a plurality of second coupling pads which overlap each other in a third direction crossing each of the first direction and the second direction and are coupled to each other, and
wherein a number of each of the first and second coupling pads arranged along the first direction in a first row that is relatively close to the external connection terminal in the second direction is greater than a number of each of the first and second coupling pads arranged along the first direction in a second row that is relatively distant from the external connection terminal in the second direction.
