Abstract
A method for manufacturing a preform having steps of obtaining a plastic material by kneading silica powder, a binder, water, and a surfactant, and obtaining a porous preform by extrusion-molding the plastic material. According to this method, a porous preform, which can produce an optical fiber exerting high mechanical strength, can be efficiently manufactured without generating bubbles
