1. A method for manufacturing a core product, the method comprising:
supplying a molten resin to a resin forming region through a resin flow path by a resin supply device, in a state where a core body is placed on a conveying jig such that the resin forming region provided in the core body communicatably connects with the resin flow path of the conveying jig;
placing the conveying jig on a collection unit by conveying the conveying jig from the resin supply device to the collection unit together with the core body, after the supplying of the molten resin;
splitting the resin solidified in the resin forming region from the resin solidified inside the resin flow path by removing the core body from the conveying jig, after the placing of the conveying jig in the collection unit;
forming a residual resin which is a residue of the solidified resin inside the resin flow path and acquiring the core product including the core body and solidified resin formed in the resin forming region, by the splitting; and
dropping the residual resin from the resin flow path into the collection unit by causing an extrusion unit to abut against the residual resin from above, after the forming of the residual resin.
