PROBLEM TO BE SOLVED: To provide a switch incorporation type secondary battery capable of always stably providing high charge accepting performance. SOLUTION: This sealed storage battery is so structured that a battery can 5 with an electrode 10 stored inside together with an alkaline solution is sealed by a metallic lid 2, a gasket 6 and a connection terminal 9 inserted into a holding part 6c formed on the gasket; a cap 1 doubling as a positive electrode terminal or a negative electrode terminal is mounted on the lid 2; and is provided with a switch mechanism S for carrying and cutting off a charge current by moving the connection terminal 9 in conjunction with expansion and constriction operation of a spring member 4 disposed in the cap 1 in response to change of battery internal pressure to bring a switch plate 8 jointed to the connection terminal 9 into contact with and separate it from the lid 2. The lid 2 is jointed to the cap 1 by welding, the connection terminal 9 is formed into a rod-like shape, and a lock mechanism is formed between the rod-like connection terminal and the holding part 6c.
