PHOTO-CURING TYPE ADHESIVE, OPTICAL PICKUP UNIT AND MANUFACTURING METHOD THEREOF |
摘要 |
An adhesive agent, which contains a light starting agent and is cured by light, is added with fillers in which the difference in refractive indices between the adhesive agent and the fillers is not larger than ±0.02. Even if the adhesive agent is added with functional fillers, this addition method allows the suppression of a lowering in the light penetrability of the adhesive agent. As a result, it becomes possible to suppress the uncuring and shrinkage of the photo-curing type adhesive agent and to perform the bonding of components with high accuracy. |
