A manufacturing method of a hydrogen storage tank stored with a hydrogen gas by including built-in hydrogen-occlusion alloys, has a stacking step of stacking plate members building up heat transfer fins, an arranging step of disposing the hydrogen-occlusion alloys between the neighboring plate members so as to form an area in which to dispose the hydrogen-occlusion alloys and an area in which to dispose none of the hydrogen-occlusion alloys, and a pressurizing step of forming air spaces sectioned by the plate members building up the heat transfer fins and containing the previously built-in hydrogen-occlusion alloys in a way that gets a part of the plate members deformed by pressurizing the plate members in a stacking direction thereof so as to restrict migrations of the hydrogen-occlusion alloys disposed in the arranging step.
