This utility model discloses a buffer component, a camera module, and an electronic device, relating to the field of imaging equipment technology. The buffer component includes a body and a buffer section, which are integrally formed. The buffer section has a deformable segment and a protrusion connected to the deformable segment. The protrusion at least partially protrudes from the surface of the body, and a recessed groove is formed on the back side of the protrusion on the surface of the body. This utility model solves the assembly difficulty problem by integrally forming the buffer section with the body, avoiding subsequent assembly of the buffer section. In use, when an external impact force acts on the protrusion of the buffer component, the deformable segment absorbs energy through its own deformation, thereby reducing the impact force transmitted to the body and its connected components. The recessed groove formed on the body provides space for the deformation of the protrusion. When the protrusion is subjected to external force, the recessed groove allows the protrusion to recess into the groove, enabling the protrusion to absorb energy.
