NOVELTY - Laminate (1A) comprises: a support (2A); a photothermal conversion layer (3A) provided on the support; a light blocking layer (4A) formed on the photothermal conversion layer; an adhesive layer (5A) formed on the light blocking layer; a flexible substrate formed on the adhesive layer; and a device element formed on the flexible substrate, where the support can be detached from the other layers by irradiating the photothermal conversion layer with light, and the adhesive layer is formed so that it covers the side surface of the light blocking layer.    USE - The laminate is useful for producing a device comprising the flexible substrate and the device element formed on the substrate (claimed).    ADVANTAGE - The laminate: provides the thin device on a flexible substrate; prevents the deterioration of the photothermal conversion layer when the substrate is treated with an alkali in the production of the device; and reduces the leakage of light into the device element site, thus enabling enhanced protection of the device.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a preparatory support for use in the laminate, comprising the support and the photothermal conversion layer;    (2) producing the laminate, comprising: (a) forming the photothermal conversion layer on the support; (b) forming the light blocking layer on the photothermal conversion layer; (c) forming the adhesive layer on the light blocking layer; (d) forming the flexible substrate on the adhesive layer; and (e) forming the device element on the flexible substrate at least through a step involving treatment with an acid or an alkali; and    (3) a method (M1) for producing a device comprising a flexible substrate and a device element formed on the substrate, comprising: step (a)-(e) as above per se; and (f) irradiating the photothermal conversion layer with light to detach the support from the other layers; and (g) separating the adhesive layer from the flexible substrate.
