The present disclosure discloses technology that detects swelling of a battery cell more effectively in a battery pack including at least one battery cell. The battery pack according to an aspect of the present disclosure includes at least one battery cell, an optical fiber sensing unit including a plate-type detection unit made of optical fibers horizontally and vertically arranged in a grid form, wherein the plate-type detection unit is deformed by deformation of the battery cell, a phororesistor to collect light reflected from the optical fiber sensing unit, and a control unit configured to determine if swelling occurred in the battery cell based on a resistance value with a change in an amount of light collected by the photoresistor.
