Disclosed are a carrier for sheet-like materials and a passivation device, solving a problems of low processing efficiency and poor consistency of processing effect of sheet-like materials. The carrier for the sheet-like materials includes a carrying assembly and at least one compressing assembly. The carrying assembly includes at least one first accommodating cavity. The first accommodating cavity includes a first opening. The first accommodating cavity is configured to accommodate a plurality of sheet-like materials stacked placed, and the sheet-like material enters and exits the first accommodating cavity from the first opening. The compressing assembly is connected to the carrying assembly and extends into each first accommodating cavity to compress the plurality of sheet-like materials in the first accommodating cavity.
