PROBLEM TO BE SOLVED : To provide a wear resistant steel sheet having excellent bending workability, and suitable as a member coming in contact with earth and sand, such as a power shovel, and to provide a method for producing the same. ŽSOLUTION : The steel sheet has a composition containing, by mass, 0.05 to 0.35% C, 0.05 to 1.0% Si, 0.1 to 2.0% Mn, 0.0003 to 0.0030% B and ≤0.1% Al, further comprising one or more selected from 0.1 to 1.0% Nb and 0.1 to 1.0% V, and comprising one or more selected from 0.1 to 1.0% Cu, 0.1 to 2.0 Ni, 0.1 to 1.0% Cr, 0.05 to 1.0% Mo and 0.05 to 1.0% W, satisfying DI*≥60, and the balance Fe with inevitable impurities : DI*=33.85×(0.1×C*)0.5×(0.7×Si+1)×(3.33×Mn+1)×(0.35×Cu+1)×(0.36×Ni+1)×(2.16×Cr+1)×(3×Mo+1)×(1.5×W+1) (1); wherein C*=C-(12/93×Nb+12/51×V).
