An objective of the present invention is to provide a fluoroalkyl group-containing compound that can be used for forming a surface treatment layer having good friction durability. As a solution, the fluoropolyether group-containing compound of the present invention is represented by the following formula (1) or (2). [In the formula, R<SP>Si</SP> is represented by the formula (S1), and each symbol is as described in the description]. R<SP>F1</SP>-X-R<SP>Si</SP> (1). R<SP>Si</SP>-X-R<SP>F2</SP>-X-R<SP>Si</SP> (2). -SiR<SP>al</SP> 2R<SP>bl</SP> (S1). |
