Abstract: An object of the invention is to provide a lid for storage battery, an injection molding method of the lid, a storage battery with the lid, and a terminal section for storage battery, which can save trouble of inserting a nut into a cavity portion of a terminal, and can prevent falling of the nut at the time of connection of an external leading wire. In a lid for storage battery in which a terminal section for storage battery 8 made up of a terminal 4 having a cavity portion, a bushing 6, and a conductive portion 7 joining both is insert-molded in a lid made of synthetic resin, and a storage battery with the lid for storage battery, an anchor portion 4T is projected at a location excluding at least a central portion of a bottom portion 4F of the terminal 4, and a nut is inserted into the cavity portion of the terminal to be fixed. Moreover, in the terminal section for storage battery, the anchor portion 4T is projected at the location excluding at least the central portion of the bottom portion 4F of the terminal 4 (e.g., the U-shaped anchor portion 4T is projected with a U-shaped joining portion 4G interposed).
