The automotive body side structure 1 of the present invention includes collision energy absorptive parts 11 provided on the outer peripheral side of the battery pack 5 in the vehicle width direction in a protruding shape toward a vehicle outside in the vehicle width direction, and a recessed portion 13 formed in a recessed shape in the side sill 3 to secure a space between the collision energy absorptive parts 11 and the side sill 3. When a collision load is input to the side portion of the side sill 3, the timing at which the side sill 3 and the collision energy absorptive parts 11 contact each other is delayed, the collision load input to the side sill 3 is transferred to the floor cross member 7 until the side sill 3 contacts the collision energy absorptive parts 11, after the side sill 3 and the collision energy absorptive parts 11 contact each other, the collision energy absorptive parts 11 absorb the collision energy to reduce a load transferred to the battery pack 5.
