To provide an apparatus for continuously producing polyisocyanate, which is able to reduce an undesirable side reaction of polyamine and polyisocyanate by allowing an immediate contact of polyamine and carbonyl chloride as soon as they are supplied so as, to reduce production of by-product and increase yield of polyisocyanate. In the apparatus, a closed line is formed by setting up in sequence along the flow direction of reaction solution, a material mixing part 8, a high shearing pump 3, a reactor 4, a liquid providing pump 5 and a cooler 6 in circle line 7. In the apparatus 1, the contact of polyamine and reaction solution is minimized in a reduced state after polyamine and carbonyl chloride are supplied to material mixer part 8, and then the reaction solution is sheared by the high shearing pump 3. Therefore, production of by-product of ureas is reduced, and the yield of polyisocyanate is increased.
