To provide a laminated body of a lithographic printing plate material and a slip sheet providing the lithographic printing plate material hardly deteriorating in printing durability despite the long term storing, and to provide a manufacturing method of the same.

The laminated body is constituted of the lithographic printing plate material having an image forming layer on an aluminum supporting body and the slip sheet laminated on the image forming layer, the smoothness of the surface contacting the image forming layer side surface of the lithographic printing plate material of the slip sheet is 25 sec or less, the smoothness of the surface opposite to the surface contacting the image forming layer side surface is 15 to 60 sec, and the gas permeating resistance of the slip sheet is 60 sec or more.
