A method for manufacturing a printing blanket including an elastic body that can be repeatedly used by removing a sheet is provided. According to the above of the present invention, the printing blanket includes an elastic body and a sheet bonded to the elastic body and performs printing by pressing the sheet against a printing object surface. The method includes a sheet fixing step of fixing the sheet at a periphery of a region in which the sheet is to be bonded to the elastic body; an elastic body placing step of placing the elastic body so that a bonding surface of the elastic body faces a bonding surface of the sheet that is fixed; a wax applying step of forming a wax layer on a surface of the elastic body; an adhesive applying step of applying an adhesive to at least one of the sheet and the elastic body that is provided with the wax layer on the surface thereof; and a pressing step of pressing the sheet and the elastic body against each other and bringing the sheet into close contact with the elastic body provided with the wax layer such that the adhesive is interposed therebetween while stretching the sheet along the surface.
