Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyurea film having more excellent chemical resistance, and to provide a method for depositing the same. SOLUTION: A coating film is formed with polyurea obtained by polymerizing alicyclic polyamine and alicyclic polyisocyanate by a vapor deposition polymerization process. In the method for depositing a polyurea coating film, two kinds of raw material monomers A, B respectively poured into two evaporation sources 21A, 21B are heated and vaporized to obtain raw material gases, the raw material gases are mixed into a gaseous mixture, the gaseous mixture is introduced into a vacuum chamber 12, the two kinds of raw material monomers are vapor-deposited and polymerized at the surface of the body 13 to be treated, and a coating film made of a polyurea film is deposited on the surface of the body to be treated.
