Abstract
Provided are a polyorganosiloxane high in elasticity, high in strength and the like. The polyorganosiloxane is a polyorganosiloxane including an M unit (RRRSiO) at a content of 10% by mol or more relative to the total of silicon and a T unit (RSiO) at a content of 80% by mol or less relative to the total of silicon, the polyorganosiloxane having an alkoxy group bound and a reactive functional group bound to silicon, wherein the polyorganosiloxane has the alkoxy group bound at a content of 0.07 to 4% by weight based on the total weight of the polyorganosiloxane and has 3 to 12 of the reactive functional groups bound on a number basis per a molecular weight of 1000 of the polyorganosiloxane, and the weight loss of the polyorganosiloxane in heating at 110° C. under a reduced pressure of 0.15 torr for 2 hours is 5% by weight or less.
