PROBLEM TO BE SOLVED: To provide a printing plate precursor for laser engraving which enables direct plate making by laser engraving, and is capable of forming a printing plate that has high engraving sensitivity, allows easy removal of engraving waste from the plate surface after plate-making, and has excellent printing durability and ink transferability. SOLUTION: The printing plate precursor for leaser engraving includes a relief forming layer including a cured resin material formed by thermally crosslinking a resin composition including at least (A) non-porous inorganic particles, (B) a binder polymer having a glass transition temperature (Tg) of 20°C or higher, and (C) a crosslinking agent.
