To provide a method for manufacturing an original plate for a lithographic printing plate with high sensitivity, excellent plate wear and especially, excellent stain resistance by which heat can be efficiently utilized for forming an image.

The method for manufacturing an original plate for a lithographic printing plate for obtaining the original plate for a lithographic printing plate by providing a particle layer on an aluminum substrate by immersing the aluminum substrate prepared by providing an anodized film on the aluminum sheet into a liquid containing hydrophilic particles with a mean particle diameter of 8-800 nm or by coating the aluminum substrate with the liquid and in addition, providing a heat-sensitive layer on which the image can be formed by exposing it to an IR laser on the particle layer, is provided.
