In a method of producing a gel sheet for electrophoresis comprising a gel membrane acting as the medium for electrophoresis composed of a hydrophilic polymer having a uniform thickness, two sheets of transparent or translucent electrical inslating films disposed on the front and the rear surfaces of the gel membrane and two pieces of spacers disposed along two facing sides of the gel membrane, an end not provided with the spacer of the gel membrane is cut off to form a slot for loading samples, the improvement which comprises, punching the gel membrane, before one surface of the gel membrane is covered with said electrical inslating film yet, to form the portion corresponding to the slot for loading samples, pressing an adhering member on the cut piece of gel membrane thereby sticking at least an edge of the cut gel membrane piece thereon, and removing the adhering member holding the cut piece of gel membrane therefrom. In the method of the invention, the cut gel membrane piece can be removed easily, surely and completely. As a result, the processing speed is raised to about four times compared to the conventional method.
