PROBLEM TO BE SOLVED: To provide a stainless steel sheet for a structural member having excellent impact absorbing properties. SOLUTION: The stainless steel sheet for a structural member having excellent impact absorbing properties has a composition comprising, by mass, 0.001 to 0.1% C, 0.001 to 0.5% N, 0.1 to 1% Si, 0.1 to 10% Mn and 10 to 30% Cr, and the balance Fe with inevitable impurities, and has a structure where a mother phase is composed of a ferrite phase, and an austenite phase or a martensite phase is present by≥5%, and in which impact absorbed energy to 10% strain in a dynamic tensile test is≥50 MJ/m<SP>3</SP>, and the ratio between proof stress in a static tensile test and proof stress in a dynamic tensile test is≥1.3.
