PURPOSE: A battery module which improves a structure in which secondary batteries are electrically connected is provided to prevent contact resistance between a terminal and a connection element from being increased. CONSTITUTION: A battery module(100) comprises a plurality of secondary batteries(110) having first and second terminals(130,140), connection elements(150) which electrically connects the secondary batteries, a connection protrusion protruded towards the terminals, and a pressing unit which presses the connection protrusion towards the first terminal. The connection element comprises a connection plate, a first connection unit protruded from one end in the longitudinal direction, and a second connection unit which is protruded from the other end. The connection protrusions are formed on the first and second connection units. |
