A battery pack (1) for an electric vehicle is attached to the bottom surface of a vehicle floor from below so that the bottom part protrudes downward from the vehicle floor. A lower case (11) that constitutes part of a case (10) is die-cast from an aluminum alloy together with an upper case (12), and has a plurality of cooling fins (66) that extend in the vertical direction integrally formed in the front wall (51) and rear wall (52) thereof. These cooling fins (66) improve the heat-release characteristics and also serve as protectors for protecting the corners of the bottom part of the battery pack (1) in the event of an impact with a curb or the like. Cooling fins (66) are provided adjacent to both sides of a safety valve (16) so as to protect the safety valve (16) from impacts.
