1. A secondary battery comprising:
an electrode assembly including a positive electrode plate and a negative electrode plate;
an exterior body having an opening and containing the electrode assembly;
a sealing plate that seals the opening;
a conductive member disposed near a side of the sealing plate facing the electrode assembly such that a first insulating member is disposed between the sealing plate and the conductive member;
a terminal that is electrically connected to the positive electrode plate or the negative electrode plate via the conductive member,
wherein the terminal is inserted through a terminal attachment hole in the sealing plate, a terminal-receiving hole in the first insulating member, and a terminal-receiving hole in the conductive member and connected to the conductive member,
wherein the conductive member has a pressing projection that projects toward the first insulating member from a portion thereof that faces the first insulating member, wherein the conductive member electrically connects the positive electrode or the negative electrode to the terminal,
wherein a distal end of the pressing projection overlaps the first insulating member in a thickness direction of the sealing plate, wherein the distal end of the pressing projection directly contacts the first insulating member,
wherein the first insulating member is located between the distal end and the sealing plate in the thickness direction of the sealing plate.
