る。(Prior Art) Conventionally, optical components made of glass have been used, but in addition to being able to easily mold even aspherical lenses, they are lightweight, inexpensive, and shock resistant. However, the use of plastics with advantages, especially acrylic resin (polymethylmethacrylate (PMMA)), is increasing. Further, due to the same advantages as described above, plastic machine parts are widely used, and plastic exterior parts are also being used in place of metal or the like. However, these plastic parts are inferior in abrasion resistance and scratch resistance as compared with glass and metal, and plastics as optical parts are inferior in light transmittance due to their large reflectance. With respect to these drawbacks, it is generally necessary to form a reinforced hard film or an antireflection film on the surface of the plastic to modify the surface. Prior to this film formation, the plastic surface is pretreated, that is, the surface is washed. Currently, as pretreatments for these, surface cleaning treatments such as dust removal, degreasing, and dehydration using a solution in the atmosphere, Freon vapor cleaning, and the like are performed.

いない。(Problems to be Solved by the Invention) However, these conventional pretreatment methods have problems such as re-contamination before the film is formed and the material of the film is limited due to the problem of adhesion. It was In other words, as a reinforced hard film, a silicon resin-based polymer film has been mainly selected so far due to the problem of adhesion, but such a polymer film has a hardness of several times that of the plastic to be the substrate. Otherwise it is not enough. Further, the film used as the antireflection film has not achieved sufficient adhesion.

ものである。(Means for Solving Problems) The present invention has been made to solve the above problems, in which the surface of a plastic lens substrate is cleaned with Freon vapor and then placed in a vacuum device to generate a high-frequency plasma by hydrogen. The feature is that the SiO 2 film is formed after the irradiation.

向上できる。(Effect of the invention) Therefore, not only is the effect of impurities present at the interface between the plastic surface and the film, which hinders the formation of a sound film, eliminated, but it also activates the plastic surface. The bond to the surface of the plastic is improved, and the film is grown soundly. As a result, the adhesion between the plastic surface and the film and the weather resistance are also excellent. Therefore, it is possible to form a SiO 2 film, which has not been practically used in the past mainly on the basis of the problem of adhesion, on the surface of the plastic, and the strength can be extremely improved.
