A perfluoro group-containing compound are represented by the following formula (I):
-Rf- is a perfluoro group; and -A represents -OH or a group:
or -CyF2y+1 or -CzF2z-1 and a perfluoro group-containing polymerizable compound represented by the following formula (II):
R1―O―CH2―CH(OH)―CH2―O―Rf―B (II)
In Formula (II), -Rf- is a perfluoro group; -B is -OH or -O-CH2-CH(OH)-CH2-O-R2, or -CyF2y+1 or -CzF2z-1; and R1 and R2 each is a dehydroxyl residue of a (meth)acryloyl group-containing compound or a vinyl group-containing compound. The hardened polymer from the compound has water-repellency, oil-repellency and adhering ability.
