<；P>；PROBLEM TO BE SOLVED: To provide an inexpensive application system having quick response performance to movement of an object and minute roughness which cannot be detected beforehand without requiring the pre-measurement of a shape of the object using an expensive system with high accuracy when materializing a special application mechanism for applying a chemical to an object having roughness on its surface, for example, skin of a human 60 or the like. <；P>；SOLUTION: The application system 1 comprises application mechanisms 10a or the like and a driving part 20. The application mechanisms 10a or the like have an application part 12 having a contact portion (top) contacting with the outside, such as the back or the like of the human 60 or the like an expansion part 14 of which one side is connected to the opposite side (inside) of the contact part (top) and which can expand and contract according to the contact of the contact part (top) with the outside, and a measurement part 16 connected to the other side of the expansion part 14 and measuring the quantity of the expansion and contraction of the expansion part 14. The driving part 20 can change the movement of the application mechanisms 10a or the like according to the quantity of the expansion and contraction of the expansion part 14 measured by the measurement part 16. <；P>；COPYRIGHT: (C)2008,JPO&INPIT
