PROBLEM TO BE SOLVED: To provide a forming device and a method of manufacturing a resin member, with which formability can be improved when forming ribs by molding a heated thermoplastic resin material between forming dies.SOLUTION: In rib-forming crevices 32 of a first forming die 24, first passages 38 are formed contiguously with the bottoms of first vertical rib-forming crevices 36X. A suction unit 40 for evacuating the inside of the first passages 38 is connected to the first passages 38. In the rib-forming crevices 32 of the first forming die 24, dead-end second passages are formed contiguously with the bottoms of second rib-forming crevices. In the forming step, the first forming die 24 and a second forming die 26 are closed, the inside of the first passages 38 is evacuated by the suction unit 40, a portion of a thermoplastic resin material 50 is made to flow into the first passages 38 and the second passages, and the thermoplastic resin material 50 is formed. |
