A method for producing an organic EL device includes the steps of: preparing an adhesive sheet on which a resin substrate is laminated, allowing the resin substrate to adhere onto a hard substrate with the adhesive sheet interposed therebetween, forming an organic EL element on the resin substrate, thereby producing an organic EL device including the resin substrate and the organic EL element, and peeling the organic EL device from the hard substrate. The adhesive sheet includes a first adhesive layer for being bonded to the hard substrate, and a second adhesive layer formed on the first adhesive layer and bonded to the resin substrate. A non-adhesive region is defined at an end portion of the resin substrate, the non-adhesive region not overlapping with the second adhesive layer but overlapping with the first adhesive layer when projected in the thickness direction.
