PROBLEM TO BE SOLVED: To provide an injection nozzle having good sealability, small sliding resistance of a valve stem, excellent response and no possibility of solidifying stock liquid while following a valve stem spring urging structure capable of obtaining desired characteristics without complicated constitution and a mixed resin liquid discharging apparatus using the same nozzle. SOLUTION: A resin liquid injection nozzle 11 comprises a valve 22a closable and openable at a resin liquid jet port 21a formed at a nozzle body 19, from an outside of the resin liquid jet port 21a and provided at a distal end of a valve stem 22 inserted into a resin liquid channel 21 in the body 19, and a spring 23 housed in a spring case 20 of the body 19 to urge the stem 22 to the closure side of the jet port 21a. When the resin liquids introduced into the channel 21 and the elastic material housing chamber 20 exceed a set pressure, the resin liquid is injected from the jet port 21a.
