The present invention provides a polyimide resin laminate, a method for producing the same, and a polyimide film with a functional layer. The polyimide resin laminate being a substrate having a carrier, which is used as a substrate instead of glass in a display or a touch panel , even when using a heat-resistant resin that can be applied to an RTR process as a carrier material, it is possible to maintain the workability in the manufacturing process and the thickness of the polyimide resin laminate as a support substrate in a display or a touch panel Degree and try to suppress warping (curling), and the support substrate can be easily separated from the support material. In the polyimide resin laminate of the present invention, a curl suppressing layer containing a polyimide resin is arranged on the side of a support layer containing a polyimide resin, and furthermore, a curl suppressing layer is peelably bonded to the curl suppressing layer. The curl suppression layer has a thermal expansion coefficient small
