Abstract: An embodiment of the application provides a battery pack, a manufacturing method therefor, and an electric device. The battery pack includes a battery unit and a support. The battery unit includes two or more secondary batteries, and has an intermediate portion and two ends. The two ends are located on both sides of the intermediate portion in a direction in which the secondary batteries are arranged. The support is configured to support the battery unit, and includes a body and a heat-resistant component arranged thereon. The heat-resistant component is arranged corresponding to at least one of the ends, so that the heat exchange amount of the end passing through the support is less than the heat exchange amount of the intermediate portion passing through the support. The temperature difference between the end and the intermediate portion of the battery unit is reduced, and the working efficiency is improved.
