The invention provides a molding method capable of reducing pollution of a base material caused by an adhesive and an adhesive. A molding method for molding a seal material (172) on a base material (140) includes: a pre-molding step of injecting a rubber raw material (150) into a cavity plate (160) having a groove (162) into which the rubber raw material (150) is injected at a temperature at which the rubber raw material (150) is not crosslinked; an application step for applying an adhesive agent and an adhesive agent (600) to the surface of the rubber material (150) injected into the groove (162) of the cavity plate (160); and a vulcanization molding step in which the base material (140) is sandwiched between the second mold (222) and the cavity plate (160), the surface of which has been coated with the adhesive and the adhesive (600), and the rubber raw material (150) is molded on the base material (140) as a seal (172) via the adhesive (600) at a temperature at which the rubber raw material (150) is crossl
