To produce an optical recording medium having a good concavo-convex shape whereby optical information recording/retrieving is stabilized. A process for producing an optical recording mediumprovided with an interlayerhaving a concavo-convex shape, which comprises a step of forming a recording layeron a substratedirectly or via another layer; a step of placing a resin material layerand a stamperhaving a concavo-convex shape for transfer, in this order on the recording layer, and curing the resin material layerin this laminated state to obtain a bonded bodycomprising the substrate, the recording layer, the resin material layerand the stamper, and a step of separating the stamperfrom the resin material layerso that the concavo-convex shape for transfer is transferred to the resin material layer, and applying surface modification treatment to promote the curing of the resin material layer, to form the interlayer
