<p>Disclosed is a fluorination treatment apparatus comprising a fluorine gas storage/feed vessel for storing and feeding a fluorine gas, a reactor for bringing a substance to be treated into contact with a fluorine gas to carry out fluorination reaction, and a fluorine gas pipe arranged between the fluorine gas storage/feed vessel and the reactor. Also disclosed is a process for producing a fluorination treated substance, comprising an enclosure step of enclosing a substance to be treated in a reactor and a fluorination reaction step of introducing a fluorine gas into the reactor to bring the substance to be treated into contact with the fluorine gas and thereby carry out fluorination reaction. According to the invention, a fluorination treated substance remarkably reduced in the light absorption loss of a substance to be treated, such as a fluoride thin film, a fluorination treatment apparatus capable of producing the fluorination treated substance, and a process for producing a fluorination treated substance can be provided.</p> |
