The first embodiment is a support for a lithographic printing plate, wherein the surface area ratios obtained from three-dimensional data by use of an atomic force microscope meets the following requirements (1-i) to (1-iii). The second embodiment is a support for a lithographic printing plate, wherein the aforementioned surface area ratios and a steepness meets the following requirements (2-i) to (2-ii). The third embodiment is a support for a lithographic printing plate, wherein the aforementioned surface area ratios meets the following requirements (4-i) to (4-iii). (1-i) a surface area ratio DeltaS<50(50) >is 20 to 90%, (1-ii) a surface area ratio DeltaS<50(2-50) >is 1 to 30%, and (1-iii) a surface area ratio DeltaS<50(0.2-2) >is 5 to 40%, (2-i) a surface area ratio DeltaS<50(50) >is 30 to 60%, and (2-ii) a steepness a45<50(0.2-2) >is 5 to 40%, (4-i) a surface area ratio DeltaS<5(5) >is 20 to 90%, (4-ii) a surface area ratio DeltaS<5(0.2-5) >is 5 to 40%, and (4-iii) A surface area ratio DeltaS<5(0.02-0.2) >is 15 to 70%.
