Abstract

PURPOSE:To prevent clogging of the fluid passage by separately forming a synthetic resin passage and a fluid passage and providing a metal having a plurality of fine communicating holes at the outlet of the fluid passage at the junction of said two passages. CONSTITUTION:In a nozzle having a synthetic resin passage and a separately formed passage 21 for a fluid of lower viscosity than the synthetic resin, a sintered metal 46 having a thickness of 2-10mm and a plurality of fine communicating holes with a diameter of 0.001-0.5mm, preferably 0.01-0.2mm, is provided at the outlet of the fluid passage at the point where the synthetic resin and the fluid join at the nozzle tip.
