Battery module and manufacturing method thereof

A battery module comprising:

• a battery group including a plurality of battery cells stacked on each other, wherein each of the plurality of battery cells includes a cell body which houses an electrode assembly and an electrode tab which protrudes from the cell body;
• a cooling plate which is located in contact with one side of the battery group to cool the plurality of battery cells;
• a case which is located on an other side of the battery group so as to surround the battery group;
• at least one bus bar which is connected to the electrode tabs of adjacent battery cells among the plurality of battery cells to electrically connect the adjacent battery cells with each other;
• a bus bar frame for securing the at least one bus bar on the bus bar frame, the bus bar frame being elongated in a longitudinal direction in which the plurality of battery cells are stacked;
• a first support member coupled to the bus bar frame and protruding toward the battery group from an inner surface of the bus bar frame;
• and
• a first sensing member coupled to the first support member and positioned between the electrode tabs of the adjacent battery cells for measuring a temperature of the battery cells,
• wherein the inner surface of the bus bar frame faces the cell body of each of the plurality of battery cells, and
• wherein at least a portion of the first sensing member is disposed between the first support member and the cell body of at least one battery cell of the plurality of battery cells.
