Disclosed in the present application are a screw, a connecting structure, a battery and an electric device. The screw has a head (203) and a threaded rod (208) connected to the head (203), and the surface of the head (203) that is located on one side of the threaded rod (208) is provided with an annular protrusion (207). When the screw is used to connect two connectors together, the annular protrusion (207) of the screw abuts against one of the two connectors, so as to form a tight-abutting structure to realize sealing. A sealant can also be applied to the position on the head (203) that is closer to a radial outer side than the annular protrusion (207), so as to improve the sealing performance. By means of the present application, even when the surface flatness of connected connectors is not sufficient, sealing can still be truly achieved while a reliable connection is provided.
