Characterize. As an apparatus used for ultraviolet irradiation, a small irradiation apparatus such as an ultraviolet lamp using synthetic quartz is sufficient, and reduction in equipment cost and working cost can be achieved as compared with the above-mentioned apparatus used for plasma processing. It is possible.

ある。The ultraviolet irradiation treatment on the molded product may be carried out by irradiating the surface of the bonded portion of the molded product with ultraviolet light having a wavelength of 200 to 400 nm as an action wavelength. It is preferable that the intensity of ultraviolet rays is high, and the atmosphere for ultraviolet irradiation is not particularly limited.
It is carried out in air at an arbitrary temperature up to ℃. It is sufficient that the irradiation time of ultraviolet rays is 2 minutes or more, preferably about 2 to 6 minutes.

向上することに起因するものと考えられる。Although the reason why the above-mentioned effect of improving the adhesiveness is exhibited is not clear, it is presumed that ultraviolet rays selectively activate the carbonyl group of the polyether ether ketone resin, or that a small amount of the ultraviolet light adheres to the surface of the molded article. It is considered that this is because the decomposition of the organic substance improves the adhesion of the molded product to the adhesive.
