The utility model provides a top cap subassembly and secondary cell. The top cap subassembly includes lamina tecti, insulator, a electrode terminals and upset piece. The insulator is fixed in the lamina tecti downside, a electrode terminals sets up in the lamina tecti and including the first basal portion that lies in the insulator downside, the upset piece is fixed in the lamina tecti, and can overturn when exceeding upset pressure, makes the lamina tecti electricity connect in a electrode terminals. Side that width direction is followed at first basal portion to the insulator is equipped with first recess, and the opening of first recess deviates from the lamina tecti, and the space intercommunication between first recess and upset piece and the insulator. Secondary cell include electrode subassembly, casing, first connection piece and the top cap subassembly. The casing is acceptd electrode subassembly and is had the opening, and the lamina tecti is fixed in the casing and seals theopening. Electrode subas
