To provide a lithographic printing plate precursor for giving a printing plate to give an image having no background stain by exhibiting high resistance in a printing machine as exposed as an image by a high intensity laser beam and exhibiting food image dissecting.

The lithographic printing plate precursor contains an electrochemically polished aluminum substrate. The polished surface of the substrate is coated with an oxide of a gel-like noncrystalline colloidal aluminum for generally introducing metal aluminum of a lower level than 5% and an intermetallic aluminum alloy and a hydroxide as well as their hydrate layers. These layers are manufactured during an electrochemically polishing step.
