摘要： A battery case, a battery, and an electronic device include a case body (10), a first cover body (110), a first insulating part (120), and a second cover body (130), where the case body (10) includes a bottom wall (140) and a side wall (150) connected to the bottom wall (140); the first cover body (110) includes a first surface and a second surface disposed opposite to each other; the second cover body (130) includes a third surface and a fourth surface disposed opposite to each other; the first surface of the first cover body (110) is connected to one end of the side wall (150) away from the bottom wall (140), and the second surface of the first cover body (110) is connected to the third surface of the second cover body (130) by the first insulating part (120); the first cover body (110) is provided with a first through hole, and the first insulating part (120) is provided with a second through hole corresponding to the first through hole. A structure that the case body (10), the first cover body (110), the first insulating part (120), and the second cover body (130) are connected in sequence can improve the overall sealing property of the battery. Therefore, the battery case, the battery, and the electronic device provided by the present application solve the technical problem that the sealing property of the battery made by interference fit between the case body (10), the sealing ring, and the case cover is poor.
