PROBLEM TO BE SOLVED: To provide an impact energy absorbing member that can appreciably absorb impact energy. SOLUTION: An impact energy absorbing member 1A, 1B has a given cross- sectional form, and absorbs impact energy when deformed under a impact load in the surface direction. The collision energy absorbing member 1A, 1B consists of a steel plate having a structure including austenite in an area rate of 60% or above, or of a steel plate including austenite adapted to generate martensite through a strain-induced transformation and having a strain hardening exponent of 0.26 or above.
