Abstract: A lithographic printing plate support of the invention includes an aluminum plate and an anodized aluminum film which has micropores extending from a surface of the anodized film opposite from the aluminum plate in a depth direction of the anodized film; the micropores each have a large-diameter portion extending from the anodized film surface to an average depth (depth A) of 75 to 120 nm and a small-diameter portion which communicates with the bottom of the large-diameter portion; the average diameter of the large-diameter portion at the anodized film surface is at least 10 nm but less than 30 nm; a ratio of the depth A to the average diameter (depth A/average diameter) of the large-diameter portion is more than 4.0 but up to 12.0; and an average diameter of the small-diameter portion at the communication level is more than 0 but less than 10 nm.
