PROBLEM TO BE SOLVED: To provide a polysiloxane compound easily convertible into a polysiloxane compound having a liberated phenolic hydroxy group, and a method of producing the same. SOLUTION: The polysiloxane compound is a reaction product obtained by hydrolyzing a silane compound represented by formula (1) with water in an amount of 0.75-10 equivalent per equivalent of alkoxy group present in the silane compound. In the polysiloxane compound, the area of T<SP>3</SP>in all signals assigned to silicon species T<SP>0</SP>, T<SP>1</SP>, T<SP>2</SP>and T<SP>3</SP>measured by<SP>29</SP>Si-NMR is 20-100%. The method of producing the polysiloxane compound includes hydrolysis of the compound represented by formula (1). In formula (1), m is an integer of 1-5; n is an integer of 0-10; k is 1 or 2; R<SP>1</SP>-R<SP>3</SP>and R<SP>9</SP>are each a 1-10C saturated aliphatic hydrocarbon substituent or an aromatic hydrocarbon group in which zero to five 1-10C saturated aliphatic substituents are bonded to a benzene ring; and R<SP>4</SP>-R<SP>8</SP>are each a hydrogen atom, a 1-10C saturated aliphatic hydrocarbon substituent, or an aromatic hydrocarbon group in which zero to five 1-10C saturated aliphatic substituents are bonded to the benzene ring.
