This gas releasing structure in a die is provided with: a sliding member that receives the pressing force of an elastic body and has an upper side having an inverted trapezoidal cross section and a lower side having a rectangular solid cross section; and a sliding member receiving body that receives the sliding body in a manner able to slide in a direction (R). While a fluid is a gas, same passes through gaps (S1, S2, S3) as flow paths and is released to the outside through gas release openings interconnecting with same, and when the fluid has transitioned to being a fused material, the sliding member moves, sealing gaps (S2, S3) and preventing any further transit of the fused material. |
