きる。Here, when the solution to be decomposed is water, the refractive index of water is 1.33 and that of quartz glass is 1.458. Therefore, quartz glass whose outer diameter changes in the longitudinal direction is introduced into this solution. By doing so, the light in the quartz glass leaks into the surrounding solution while transmitting in the length direction. The tapered shape makes the light leakage uniform, and is easy to manufacture and realistic. When quartz glass or another material is used as the photoconductor, the difference in refractive index from the liquid to be decomposed can be selected by appropriately adding a dopant, and the ratio of light leakage can be adjusted.
