Lithographic printing plate precursor, method of producing same, lithographic printing plate precursor laminate, plate-making method for lithographic printing plate, and lithographic printing method

A lithographic printing plate precursor comprising:

• a hydrophilized aluminum support;
• a water-soluble or water-dispersible negative type image recording layer provided on the aluminum support;
• and
• a protective layer on the image recording layer,
• wherein an arithmetic average height Sa of a surface of an outermost layer on a side where the image recording layer is provided is in a range of 0.3 μm to 20 μm,
• the image recording layer contains an infrared absorbing agent and a thermoplastic polymer particle,
• the protective layer is an outermost layer and has a plurality of protrusions containing, as a main component, a polymer compound on the protective layer;
• the aluminum support includes an aluminum plate and an aluminum anodized film disposed on the aluminum plate,
• the anodized film is positioned closer to the image recording layer side than to the aluminum plate,
• the anodized film has micropores extending in a depth direction from the surface of the image recording layer side, and
• the average diameter of the micropores in the surface of the anodized film is in a range of 10 nm to 150 nm.
