A battery wrapping film, a battery component, and a terminal, where a first glue dot area and a second glue dot area are disposed in a first plane of the battery wrapping film to connect the battery and the battery wrapping film. The first glue dot area corresponds to a protruding area in a first plane of a housing, and the second glue dot area corresponds to a recessed area in the first plane of the housing. Hence, sparse glue dots are dispensed on the wrapping film corresponding to the protruding area on the housing, and dense glue dots are dispensed on the wrapping film corresponding to the recessed area on the housing, ensuring that the battery of the battery component is uniformly forced and is easy to detach.
