To provide a control valve type lead storage battery with long life by restraining occurrence of a crack and a hole in an inter-cell connection body even at a trickle use for long period, and improving reliability of an inter-cell connection part, as well as to provide an inter-cell connection structure with excellent productivity not bringing force a defect like fall-off of the connection body in its manufacturing process.
Of a pair of electrode plate groups housed in adjacent cell chambers 7 of the control valve type lead storage battery, a positive electrode shelf 8 of one electrode plate group 1 and a negative electrode shelf 9 of the other electrode plate group 1' are made to oppose to each other with an interval 6, into which, a connection body 11 having a U-shaped connection part is fitted, and the connection body 11 is welded to the shelf with pressure by its spring characteristics.
