Axial impact energy absorbing performance at the time of collision is to provide an excellent impact energy absorbing member for a car. It has more than 980 ㎫ TS, also by processing the high strength steel sheet forming the n value and the limit bending radius Rc, satisfying Rc≤1.31 × ln (n) +5.21, and the impact energy absorbing member for a car. By using this high strength steel sheet having the same properties, even when TS is greater than or equal to 980 ㎫, to stabilize the buckling members at the time of vehicle collision in the axial direction it can be deformed in crushing the feather. In addition, high strength steel sheet to be used is, in mass%, C: 0.14% ~ 0.30%, Si: 0.01 ~ 1.6%, Mn: 3.5 ~ 10%, N: 0.0060% or less, Nb: containing 0.01 to 0.10% composition and, less than 30% to 70% of ferrite phase average grain diameter 1.0 ㎛ to volume ratio for the entire organization, and the second phase comprises at least 10% residual austenite phase in a volume ratio to the entire at least tissues, and also residual austenite it is desirable to have less than 1.5 ㎛ tissue on the average interval.
