PROBLEM TO BE SOLVED: To reduce the thickness of an entire battery pack to a minimum without varying the thickness of a thin battery. SOLUTION: The battery pack comprises the thin battery 2 mounted in an outer case 1 and an insulating sheet 7 bonded to the surface of the thin battery 2. The outer case 1 is provided with an opening 3 for exposing the front and back of the thin battery 2 to the outside and is about as thick as or thinner than the thin battery 2. The outer case 1 has a first case 1A and a second case 1B divided for the front and back of the thin battery 2, respectively. The first case 1A and the second case 1B are each formed in the shape of a rectangular frame consisting of a side case part 1a covering a side of the thin battery 2, and an end case part 1b covering an end face of the thin battery 2, with an outer corner part of the side case part 1a formed as a curved face part. The insulating sheet 7 is bonded to the outer surfaces of the side case parts 1a of the first and second cases 1A, 1B to connect the first and second cases 1A, 1B to each other.
