PROBLEM TO BE SOLVED: To provide an injection molding apparatus for thermosetting resin capable of preventing thermosetting liquid molding material from being cured in accordance with overheating of a nozzle and, at the same time, and preventing the thermosetting liquid molding material from leaking out of an aperture between the nozzle and a mold. SOLUTION: A sealing member 44, which comes to contact with a spool bush 22 when the thermosetting liquid molding material 8 is injected, is fitted to the distal end of a nozzle body 41. The sealing member 44 has thermal insulation performance, suppresses a temperature rise of the nozzle body 41, is interposed between the nozzle body 41 and the spool bush 22, and prevents the thermosetting liquid molding material 8 from leaking out of the aperture between both of them.
