The manufacturing apparatus of a resin molded product has a feed block that sets a layer configuration of the resin molded product obtained by molding a plurality of molten resins. The feed block includes a feed block body having a through hole, and a plurality of replacement blocks that are removably fitted into the through hole and have layer configuring passages corresponding to different layer configurations. A replacement block before change is pushed out of the through hole by a replacement block having a layer configuring passage corresponding to a layer configuration after change, thereby changing the layer configuration. This allows an easy change of a layer configuration, and in particular, prevents degradation of resin due to heat or oxidation, and reduces time for the change and a material loss even when a significant change of the layer configuration such as a change of a layer arrangement is performed.
