Silane coupling agents which are so high in heat resistance, durability, releasability, and antifouling properties that no decrease in contact angle is observed even after exposure to an atmosphere having a temperature of 350°C or higher for 4 hours or longer. The silane coupling agents have a biphenylalkyl group and are represented by the following general formula (1). The silane coupling agents are so high in heat resistance, durability, releasability, and antifouling properties that surfaces modified with these compounds show no decrease in contact angle when exposed to an atmosphere having a temperature of 350°C or higher for 4 hours or longer. The coupling agents have an extraordinary effect and usefulness. (1) [In the formula (1), Rf represents perfluoroalkyl of F(CF<SUB>2</SUB>)<SUB>n</SUB>, wherein n is an integer of 1-14, desirably 1-12, preferably 4-12, more desirably 4-10.] |
