PROBLEM TO BE SOLVED: To provide a latex of a polyorganosiloxane useful as a raw material for various kinds of polymeric materials such as a fiber treating agent, an adhesive, a sealant agent, especially a resin reinforcing agent. SOLUTION: The latex of the polyorganosiloxane comprises polyorganosiloxane particles obtained by polymerizing an organosiloxane mixture composed of a 4-membered ring organosiloxane and other organosiloxanes. The polyorganosiloxane particles have 150-800 nm mass-average particle diameter (d<SB>w</SB>) and≤1.2 ratio (d<SB>w</SB>/d<SB>n</SB>) of the mass-average particle diameter (d<SB>w</SB>) to the number-average particle diameter (d<SB>n</SB>). A method for producing the latex of the polyorganosiloxane is provided. COPYRIGHT: (C)2008,JPO&INPIT
