An insert component (2) is located at a predetermined position between a pair of halves of a mold (1) in an open state while being held by a support (12) for holding the insert component (2) outside the mold. A tubular molten resin (4) is extruded through a die (3) between the pair of halves of the mold (1) to dispose the insert component (2) in the interior space (13) of the molten resin (4). By clamping the mold (1), the insert component (2) is covered with the tubular molten resin (4) in conformity with the contour thereof to result in an insert-mold product (20).
