PROBLEM TO BE SOLVED: To provide a terminal structure contributing to the reliability improvement of a high-capacity lead storage battery whose electrolyte solution is required not to ooze out over a long period. SOLUTION: The terminal structure includes a lead-made or lead alloy-made bushing 2 integrally formed with a synthetic resin-made electrolytic bath lid 1, an electrode pole which is inserted through a through-hole of the bushing 2 and collects the current of an electrode plate group, and a terminal connected with the electrode pole and the bushing 2. The opposing surface of the bushing 2 opposite to the synthetic resin part of the electrolytic bath 1 is coated with an acid-resistive resin 3 and made a mirror surface.
