However, these fibers have a large transmission loss in the infrared region and do not transmit light with a wavelength of 2 to 5 μm or more, so they are unsuitable as fibers for infrared light.

45-7° As a result, it can be seen that the infrared fiber having the buffer layer has excellent optical properties. In addition, infrared light fibers made of metal halide crystals bend due to plastic deformation, so if this fiber is bent repeatedly, the bends will become wrinkled in some areas, resulting in small local bending radii and large transmission losses. Similarly, from the measurement results of CO2 laser light transmittance after repeated bending with a bending radius of 20 crn, it was found that infrared light fibers without a buffer layer tend to have lower transmittance and larger variations. However, in the fibers of the present invention having a buffer layer (Examples 1 to 3), no decrease in transmittance or variation was observed. Although the example uses polyvinylidene fluoride, the present invention is not limited thereto.
