A battery structure includes a main body and a pulling member. The main body has a first outer surface and a second outer surface which are parallel to each other. The pulling member is connected to the first outer surface and the second outer surface and forms a holding portion extending from the main body. When taking the battery structure out of an electronic device, a user only needs to pull the holding portion, and then the main body can be separated from the electronic device. Whatever the pulling direction is, the pulling member cannot be destroyed, so the convenience in usage and durability can be increased.
