Disclosed is a wear-resistant steel sheet comprising the following components (by mass%): C: 0.13 to 0.18% (inclusive); Si: not less than 0.5% and less than 1.0%, Mn: 0.2 to 0.8% (inclusive), P: 0.020% or less, S: 0.010% or less, Cr: 0.5 to 2.0% (inclusive), Mo: 0.03 to 0.30% (inclusive), Nb: more than 0.03% and not more than 0.10%, Al: 0.01 to 0.20% (inclusive), B: 0.0005 to 0.0030% (inclusive), and N: 0.010% or less, with the remainder being Fe and unavoidable impurities, wherein the chemical composition fulfils the requirements that the HI value is 0.7 or more and that the Ceq value is more than 0.50. The steel sheet has an HB (Brinell hardness) value of 360 to 440 (inclusive) at 25°C.
