A novel cyclic polyorganosiloxanesilazane, which is a siloxane oligomer having satisfactory reactivity, and is useful as a silylating agent that does not generate reaction residues. Also, a method of producing the cyclic polyorganosiloxanesilazane. The cyclic polyorganosiloxanesilazane is represented by general formula (1) shown below:
