The invention discloses a tool steel roller for rolling a medium-thickness plate and a manufacturing method thereof. The tool steel roller comprises a core part of nodular cast iron, a roller neck and a roller body work layer, wherein the roller body work layer comprises the following chemical components in percentage by weight: 1.60-2.2% of C, 0.50-1.00% of Si, 0.50-1.00% of Mn, 10.00-15.00% of Cr, 0.20-1.80% of Ni, 0.20-1.50% of Mo, 0.20-1.00% of V, less than or equal to 0.03% of S, less than or equal to 0.05% of P and the balance of Fe and unavoidable impurities. According to the tool steel roller and manufacturing method disclosed by the invention, by designing a reasonable alloy composition and processing technology, the mechanical properties of a working roller of a rolling mill are effectively improved, and the wear resistance and millimeter rolling amount of the roller are increased; moreover, the tool steel roller has good hot-crack resistance, and the working efficiency of a medium-thickness plate rolling mill can be remarkably improved.
