The jacket is of a multilayer laminate structure made by disposing a polyolefin film on the inside contacting the plate assembly and laminating a film of thermoplastic synthetic resin in two or more layers on the outside thereof. According to the present invention, the plate assembly can be encased with an unexpensive jacket of a simple construction, and the joint of the jacket to the pole posts of the plate assembly is strengthened to offer a leak-proof enclosed lead storage battery.
