An automotive body side structure 1 according to the present invention includes a side sill 3 extending in a vehicle length direction, and a battery pack 5 disposed vehicle inside in the vehicle width direction relative to the side sill 3, and includes collision energy absorptive part 11 provided in a protruding shape toward vehicle outside in the vehicle width direction on an outer peripheral side in the vehicle width direction of the battery pack 5, having a steel sheet having a tensile strength of 270 MPa-class or more and 340 MPa-class or less and a plate thickness of 1.0 mm or more and 1.4 mm or less, wherein at a time of a side collision in which a collision load is input to the side sill 3 from vehicle outside in the vehicle width direction, after the side sill 3 deformed by the input collision load comes into contact with the collision energy absorptive part 11, the collision energy absorptive part 11 is deformed to absorb collision energy to reduce a load transferred to the battery pack 5.
