PROBLEM TO BE SOLVED: To provide an insert molding method not generating the trace of fixing insert parts on an insert position on an insert molded product. SOLUTION: First and second insert parts A and B are stored respectively in a cavity between a first mold block 8 and a second mold block 9 constituting a resin molding die, and the resin is injected from a gate 6. The resin from the gate 6 is passed through a through-hole 10 formed on a second insert part and injected into the cavity, and the first insert part A is pressed on the first mold block 8 by the injection pressure, while the second insert part B is pressed on the mold block 9 by the reaction pressure to fill the resin in the cavity, and insert molding can be carried out without using a means for fixing the insert parts A and B respectively.
