To provide a fluorinated compound, which can readily form a thin film having a hydrophobic/hydrophilic pattern, by employing an ultraviolet light having a relatively low energy.
A thin film having a hydrophobic/hydrophilic pattern is formed by irradiating a thin film formed by employing a fluorinated compound represented by the following formula 1 (in the formula 1, each of R
1
, R
2
, R
3
and R
4
which are independent of one another, is a hydrogen atom, a halogen atom or a monovalent organic group, provided that at least one of them is a monovalent organic group having fluorine atoms, and R
5
is a hydrogen atom or a monovalent organic group, R
6
is a monovalent organic group, and A is a hetero atom) with ultraviolet light.
