Abstract

An organic membrane is stretched over, or adhered to, a frame or a substrate, and that part of the membrane which extends out of the frame or substrate is cut by bringing an injection syringe-like needle into contact with, or approach to, the lateral end surface of the frame or substrate and while moving the needle along said lateral end surface, injecting an organic solvent from the needle and dissolving said membrane along the lateral end surface of the frame or substrate. By this method, the organic membrane can be cut without generating foreign matter such as cut dust.
