PROBLEM TO BE SOLVED: To provide a polypropylene resin laminated body having remarkably favorable coating adhesion even if there is no undercoating of a primer etc. and having excellent moldability and easy stretchability. SOLUTION: The polypropylene resin laminated body is composed by laminating a base layer composed of a crystalline polypropylene resin, and at least a polypropylene resin composition on the base layer, and satisfies the followings (1) and (2). (1) In the skin layer, an O/C (an oxygen atom presence ratio to a carbon atom) by the X-ray photoelectron spectroscopy (XPS) of an opposite surface to the laminated surface with at least the base layer is 0.001 or higher, and (2) the tensile breakdown elongation of a sheet composed of a polypropylene resin composition which constitutes the skin layer is 250% or higher.
