A process of producing a hollow resin-molded article includes: arranging covers on inner walls of mold halves, the covers having shapes corresponding to the inner walls; introducing a pair of sheets of thermoplastic resin each facing the cover arranged on the inner wall of a corresponding mold half; blowing air into a space between the sheets to cause the sheets to respectively contact the covers arranged on the inner walls, and thereby fusion-welding the sheets to the covers; and closing the mold halves; and cooling down the covers and the sheets in a state where the mold halves are closed. In the step of arranging, there are uncovered portions of the inner walls that are not covered by the cover. In the step of closing, there are mold contact portions of the sheets that respectively contact the uncovered portions directly and the mold contact portions are fusion-welded to each other in an overlapping manner.
