An object of the present invention is to form a strong coating on the surface of a substrate that is curable at room temperature and without a primer, and the coating is useful as a surface treatment agent that maintains good performance such as water and oil repellency and releasability over a long period of time. A perfluoropolyether modified polysilazane is provided. A perfluoropolyether-modified polysilazane consisting only of a unit represented by the following formula (1): [Chemical 1] (In the formula, Q is a divalent organic group, m is an integer of 1 or more, and x and y are integers of 1 to 3, respectively.)
