PURPOSE:To easily form the endoscope which is provided at least a pore for a light receiving path in a transmission path for an illuminating light by pouring a plastic material for the light transmission plastic together with introducing the pipe for forming the pore in a forming die. CONSTITUTION:The lengthy pipe 1 is introduced in a center of the forming die 2 to form the pore for the light receiving path. Then, a liquid prepolymer, a polymerizable monomer or a mixture of polymerizable monomers are poured in the forming die 2 as the starting material 3 of the light transmission plastic for constituting the transmission path for the illuminating light, thereby enveloping around the pipe 1 introduced in the forming die 2 with the starting material 3, and subsequently, the starting material 3 of the light transmission plastic poured in the forming die 2 is polymerized to cure it. After curing the prescribed material 3, the cured material is released from the forming die 2 whereby the endoscope A which is formed the pore 5 for the light receiving path in the transmission path 4 for the illuminating light due to the pipe 1 is obtd. |
