1. A cooling member for a battery module having a cooling plate in contact with a plurality of battery cells to transfer heat emitted from the battery cells to the outside, the cooling member for a battery module, comprising:
a predetermined pattern formed to accommodate at least a portion of the outer surface of the battery cell on the main surface along the longitudinal direction;
wherein the predetermined pattern has a cross-section, wherein the cross-section comprises a plurality of a peaks and a plurality of valleys formed alternately;
an insulating heat dissipation layer having a thickness of 300 to 1,000 μm and a Shore OO hardness of 35 to 50 for covering at least a part of an outer surface of the cooling plate so as to be interposed between the battery cell to be accommodated on the predetermined pattern and the cooling plate, wherein the insulating heat dissipation layer is a coating layer, wherein the coating layer comprises an insulating heat dissipation filler dispersed within a silicone-based matrix, wherein the silicone-based matrix is cross-linked by addition polymerization of polydimethylsiloxane containing a vinyl group at the terminal; and
a silicone-based primer layer disposed between the coating layer and the cooling plate.
