Abstract
There are provided a laminate, a preparatory support, a laminate production method and a device production method which make it possible to successfully produce a thin device on a flexible substrate which is likely to bend or break. A laminate 1A includes: a support 2A; a photothermal conversion layer 3A; a light blocking layer 4A; an adhesive layer 5A; a flexible substrate 6A; and a device element 7A, wherein the support 2A can be detached from the other layers by irradiating the photothermal conversion layer 3A with light, and wherein the adhesive layer 5A is formed such that it covers the side surface of the light blocking layer 4A.
