The invention provides a structural base which has a uniform and thin coating film that is highly inhibitory to biomaterial adhesion and does not adversely affect measurements such as optical measurement, and a method for producing such structural bases.A structural base includes a coating film on at least a portion of the surface thereof, the coating film having a difference between the maximum film thickness and the minimum film thickness of not more than 1000 Å. A method of the invention produces such structural bases. The coating film includes a copolymer including a repeating unit containing a group represented by the following formula (a), and a repeating unit containing a group represented by the following formula (b) (wherein U, u, U, U, Uand Anare as defined in the description and the claims). |
