Abstract

PURPOSE:To facilitate control over refractive-index distribution by light and to miniaturize a transmitter by forming a preform member by processing a sheetlike member, made of a photopolymerized plastic material, in a prescribed way. CONSTITUTION:Sheetlike member 1 made of a photopolymerized plastic material is irradiated with light having a wavelength in the photosensitive wavelength range of member 1 while light intensity or light irradiation time is varied as the irradiation point moves from one end side of member 1 to the other end side. Then, the degree of photopolymerization is varied in the width direction of member 1 and after sheetlike member 1 having been irradiated with the light is fixed and then wound around axial core starting member 2 with the high-refractive-index end side outside to form perform member 3. Next, member 3 is drawn by being heated to obtain a flexible light transmitter having the refractive-index distribution varying continuously in the radius direction.
