Urushi (Japanese lacquer) is a natural material that is not only has decorative beauty but also has many useful features for engineering field, such as electrical resistance and water resistance. In this research, we have created electronic circuit using Urushi as an insulating material and structure (Urushi Circuit). In addition, we indicated that it is possible to provide the interactive features while enjoying original beauty and texture of Urushi. We aimed at a multilayered circuit to create a high performance Urushi Circuit. Thus, we proposed and developed an Urushi processing method (Ultraviolet Irradiation Method) by ultraviolet light (UV). In this paper, the accuracy of the verification experiment is enhanced to improve the processing accuracy of the Ultraviolet Irradiation Method. Based on our data, we created a model to describe Urushi dissolved to facilitate good reproducibility and controllability. Next, the reproducibility of our model was verified by performing UV irradiation tailored to the target value. Further, we fabricated an Urishi Dissolution System using Ultraviolet Irradiation Method. We confirmed the feasibility of our system by performing UV irradiation tailored to the target value at optional positions.
