The present application provides a secondary battery, a battery module, and a device for using a secondary battery as a power source. The secondary battery includes: a casing; an electrode assembly, disposed in the casing and including a main body and a tab; a cap assembly, including a cap plate connected with the casing and an electrode terminal disposed on the cap plate; and a current collecting member, including an adapting piece and a connecting component, the connecting component and the adapting piece provided separately and connected with each other, the adapting piece connected with the electrode terminal, and the adapting piece including a guiding section, which is located on a side of the main body along a length direction of the secondary battery and extends along a direction perpendicular to the length direction; the connecting component includes a current collecting section which is configured to be connected with the guiding section and a tab connecting section which is configured to be connected with the tab, the current collecting section is disposed between the guiding section and the main body, and the connecting component has a rigidity less than that of the guiding section, so that deformation of the guiding section toward the main body can be reduced when a portion of the connecting component connected with the tab is bent with respect to the length direction, thereby reducing the possibility of a film or powder of the electrode plate being peeled off due to the squeezing of the guiding section on the electrode plate.
