A battery pack with massage function includes a case, a battery cell, an electrical connector, a switch, a moving body, and an electrical actuator assembly. The case has an accommodation space and a through hole communicating the accommodation space. The battery cell is disposed in the accommodation space. The electrical connector is disposed on a surface of the case and is electrically connected to the battery cell. The electrical connector is used for connecting with a power receiver of an electronic device for supplying electrical power from the battery cell to the electronic device. The switch is electrically connected to the battery cell to be selectively switched to a close-circuit-state or an open-circuit-state. The moving body is capable of moving reciprocally via the through hole. The electrical actuator assembly is connected to the battery pack via the switch to generate a driving force to move the moving body reciprocally.
