From the viewpoints of environmental problems, resource problems, and safety to the human body, it has been said that natural polymers have been reviewed, and many studies have been conducted, but it seems that they are still in the research stage. This time, I reviewed the applications that are heavily used due to the characteristics of natural adhesives even in today. In Japan, innovation has long been understood as technological development since its introduction. However, according to Schumpeter, who originally preached innovation as the principle of economic development, and Drucker, who proposed the opportunity,“ new products and new products” by“ new combination” including not only technology but also existing ones, systems, methods, etc. “Creation of services” “Introduction of new production methods” “Entering new markets” “Acquisition of new resources”“Realization of new organizations”. It seems that innovation opportunities can be found by re-recognizing the applications that are still being used because of their characteristics.
