Summary: | A method for injection molding comprises the following steps: a step of preparing a first mold (41), a second mold (46), and a third mold (47), a step of sandwiching a separator single body (16) by the first mold (41) and the second mold (46), a step of injecting silicone rubber (59) into a front-side cavity through a gate (52) to form a front-side formed layer, a step of replacing the second mold (46) with the third mold (47) while the front-side formed layer is soft, and a step of penetrating the front-side formed layer by injection pressure of the silicone rubber (59) injected through the gate (52), filling the silicone rubber (59) into a back-side cavity through a penetration hole (30), and forming a back-side formed layer. |
